Array to lookup multiple columns and take another columns information - excel

I am trying to lookup a part number in a separate table array, the same value could be in multiple rows. The formula should find each instance of the value in the other table, move to a date column and determine which months the value exists in and which row it belongs to. The entire table B3:F15 should be automated. I have attached an image with proper explanation of what I am trying to accomplish if at all possible.
The formulas would be entered into B3:F15. These are the cells where the data will get pulled into. Each row will search for its corresponding Part Number in column A. I.e, B3 to F3 is only looking for A3 data. The rows are used to determine if a Part number in L2:P4 matches their row value in Column A and if was used in that month belonging to months B2:F2. If the Part number was used in the corresponding month then it will output the Plant # from Column I. In some cases the Part numbers in L2:P4 can exist in multiple rows, but they are unique to each column.
As an example I have manually filled in data for PN1001 and PN1021. For PN1001, this belongs to B3:F3. Each cell in B3:F3 will search the array L2:P4 and realize it is found only once and in M4, so it will look at the dates from its row, J4 and K4, and determine which months it was used in. Since it was used in Jan, Feb, and Mar, it will output the Plant # into D3, E3, F3. In the example of PN1021 it is the same but in this case PN1021 exists in L2 and L4, so it will take the date of J2,K2, and J4,K4.
Some Part numbers can be a combination of letters and numbers, some may just be numbers.
In terms of how to build the formula I am not sure what combination of Index/Match/Lookup I should be using. My theory is that each cell in B3:F15 would include a formula that be =MATCH(Lookup(columnA with L3:P4)) (but how do you get it to lookup multiple instances??) Some research lead me to use this concept to find multiple instances and point to the row #.
SMALL(IF(Lookup Range = Lookup Value, Row(Lookup Range),Row ()-# of rows below start row of Lookup Range)
Once I can find each instance, then Index the row and compare if the cell in B3 is greater than J3 and less than K3 to determine the months which should have a value entered. IFYES, then output column I from the row number.
If you have any better solutions or ideas to perform this action then please provide feedback. Thanks in advance for the support.

I think the formula below will do what you want. I created a table out of your I1:P4 data, and used structured references, as I find it easier to follow.
B3: =IFERROR(
INDEX(partsTbl,
MAX(
($A3=partsTbl)*
(B$2>DATE(YEAR(partsTbl[[Test Start Date]:[Test Start Date]]),MONTH(partsTbl[[Test Start Date]:[Test Start Date]]),0))*
(B$2<DATE(YEAR(partsTbl[[Test Finish Date]:[Test Finish Date]]),MONTH(partsTbl[[Test Finish Date]:[Test Finish Date]])+1,1))*
ROW(partsTbl)-ROW(partsTbl[#Headers])),
1),
"")
$A3=partsTbl returns a 2D array like {FALSE,FALSE,TRUE,FALSE;FALSE,FALSE, …} to find the part number in the table
Since your start/finish dates in the partsTbl are not always at the beginning/end of the month, we need to convert them to such before we compare the dates in B2:F2
(B$2>DATE(YEAR(partsTbl[[Test Start Date]:[Test Start Date]]),MONTH(partsTbl[[Test Start Date]:[Test Start Date]]),0))
And similar for the end of the month.
We now have a 2D-array of {FALSE,FALSE,TRUE,FALSE...} where the TRUE matches the part number as filtered by the dates.
ROW(partsTbl) returns a matching array of the row numbers in the table (and we subtract the row number of the Header row to determine the row within the data).
When we do our multiplication, we then get an array where the largest value will be the desired row
INDEX, referencing column 1, will then return the appropriate Plant #

Value -?
Part of the problem you may be having is dates. Make sure your dates are excel dates and not string/text that looks like a date. Simply changing the formatting of a cell does not make it a date, it simply tells excel how to try and display the information in a cell.
Dates in excel are stored as integers and they represent the days since 1900/1/1 with that date being day 1. One of the easiest ways to test if a cell contains a date or a string is:
=ISTEXT(A1)
or
=ISNUMBER(A1)
Where A1 is the cell with the date to be tested.
If it returns TRUE for the first formula it is a string/text. FALSE means it is a number. The opposite TRUE and FALSE results apply for the second formula.
In your formula's when you have something between quotes "", it will be interpreted as a string. SO something like "<=19/05/26" mean its looking for a string less than that, not a date less than that. For doing a date comparison, either concatenate the text comparison with with a cell containing a date to compare to "<="&B2 where B2 has the date or if you want to hard code it use something like "<="&Date(19,05,26)
In order to make the following solution work, your dates all need to be stored as a number. AKA Excel serial date format.
Based on the data being layed out as per the image below, you can use COUNTIFS, INDEX, and MATCH to get the date your are looking for. I recommend find your count of D and N separately and adding them together after for a total. However if you want it in a single cell formula solution it can be achieved as well as demonstrated by the results in column N. however the formula starts to get long and can be difficult potentially read/maintain at a later date.
The core of the solution will be the COUNTIFS functions. The format of the COUNTIFS function is as follows:
COUNTIFS(Range to count 1, Criteria 1, Range to count 2, Criteria 2,...,Range to count n, Criteria n)
Let start building your formula one criteria at a time. The first Criteria will be all dates that are greater than or equal to the from date. If you only want the dates after the from date, drop the equal sign or the criteria.
=COUNTIFS($A$2:$A$4,">="&$G2,
Note the $ to lock the cell references. This is done so that when the formula gets copied, the column or row references beside the $ does not change.
Then second criteria is similar to the first except you want to grab all the dates less than or equal to the through date. Again include/drop the equal sign to suit your needs.
=COUNTIFS($A$2:$A$4,">="&$G2,$A$2:$A$4,"<="&$H2,
The next criteria will be to get all the cells that match D or N the column header. Lets just focus on D for now. The tricky part is to define which column to look in. For now lets call the column to look in XXX which will make the formula become:
=COUNTIFS($A$2:$A$4,">="&$G2,$A$2:$A$4,"<="&$H2,XXX,J$1)
OR
=COUNTIFS($A$2:$A$4,">="&$G2,$A$2:$A$4,"<="&$H2,XXX,"="&J$1)
NOTE: both formulas are the same. When no comparison operator is provided
it is taken as "=" by default.
Now in order to define XXX, INDEX and MATCH will be your friends. An important side note about INDEX is that it does not directly return the value of a cell but instead returns a cell address which in turn pulls a cell value. The basic format of INDEX is:
INDEX(Range to look in, Range's ROW to look in, Range's COLUMN to look in)
That is for a 2 dimensional range. If your range is 1 dimensional, either just a column or just a row, then only the second argument "Range's Row..." need to be provided and it represents how far down the list to go.
What gets interesting about a 2D INDEX is that when 0 is provided for ROW to look in or the Column to look in, instead of throwing an error, it instead returns all rows or columns. THIS IS IMPORTANT because you want all rows of just 1 specific column. That mean your INDEX formula is going to start to look like:
INDEX($B$2:$E$4,0,SPECIFIC COLUMN NUMBER)
So now you need to find a specific column number. That is where MATCH will be your friend. MATCH takes the following format:
MATCH(Value to find, 1D range to look in, what type of search)
You already know you are going to try and match your shift column so that will be your look up value, and the range to look in will be your column headers. The type of search you will want in this case is an exact match which is represented by 0. That means your MATCH formula will look like:
MATCH($I2,$B$1:$E$1,0)
Now to combine the various pieces, throw the MATCH formula into your INDEX and replace the "SPECIFIC COLUMN...". Your INDEX will now look like:
INDEX($B$2:$E$4,0,MATCH($I2,$B$1:$E$1,0))
And the formula above can now replace the XXX in your COUNTIFS formula and you will get:
=COUNTIFS($A$2:$A$4,">="&$G2,$A$2:$A$4,"<="&$H2,INDEX($B$2:$E$4,0,MATCH($I2,$B$1:$E$1,0)),J$1)
Place the above formula in J2 and copy the cell down and to the right.
In L2 use one of the two formulas to get the total of D and N in the date range:
=SUM(J2:K2)
OR
=J2+K2
Now to get your formula all in one cell, look at the second formula above. You can simply go to the contents of cell J2 and copy the entire formula. Then edit cell L2 and replace the cell reference for for J2 with the copied formula. Repeat the process by copy formula in K2 and replacing the reference to K2 in L2. You will wind up with a formula that looks like:
=COUNTIFS($A$2:$A$4,">="&$G2,$A$2:$A$4,"<="&$H2,INDEX($B$2:$E$4,0,MATCH($I2,$B$1:$E$1,0)),J$1)+COUNTIFS($A$2:$A$4,">="&$G2,$A$2:$A$4,"<="&$H2,INDEX($B$2:$E$4,0,MATCH($I2,$B$1:$E$1,0)),K$1)
Much longer and harder to read which is why I recommend breaking the formula down into its parts for D and N separately.
Now as an alternate method you could use SUMPRODUCT and get into array operations. Your SUMPRODUCT formula to place in I2 and copy down and right could be:
=SUMPRODUCT(($A$2:$A$4>=$G2)*($A$2:$A$4<=$H2)*(INDEX($B$2:$E$4,0,MATCH($I2,$B$1:$E$1,0))=J$1))

Count rows where date is inside current month with multiple criteria

I'm trying to create a formula that checks the date column of a row and checks it is within the current month, then checks a separate column in a row and checks it is equal to some text, the formula would then output a count of instances where that is true.
For reference, the columns are named as two ranges, LeadDate and LeadAcquisitionChannel.
[edit] The Refers to: definitions are:
'LeadDate Refers to:
=OFFSET('Enquiry Log'!$A$2,0,0,COUNTA('Enquiry Log'!$A:$A),1) 'LeadAcquisitionChannel Refers to:
=OFFSET('Enquiry Log'!$J$2,0,0,COUNTA('Enquiry Log'!$J:$J),1)
I ran the date check with following formula:
=COUNTIF(LeadDate,">"&EOMONTH(TODAY(),-1)
Which was successful in telling me how many entries fall within the current month.
So I assumed I could then add the multiple criteria in a COUNTIFS like this:
=COUNTIFS(LeadDate,">"&EOMONTH(TODAY(),-1),LeadAcquisitionChannel,B27)
B27 being a cell containing the text I want to check for.
This formula returns me a #VALUE! error.
Any ideas as to why this is happening or whether there is an alternative method I can use?
The key here lies in the Refers to: definitions for both LeadDate and LeadAcquisitionChannel as COUNTIFS requires that each criteria range be the same size and shape of cells.
For a dynamic list of dates that grows when new dates are added:
='Enquiry Log'!$a$2:index('Enquiry Log'!$a:$a, match(1e99, 'Enquiry Log'!$a:$a))
For a matching dynamic list of other information in an adjacent column use the same terminating row like this:
='Enquiry Log'!$j$2:index('Enquiry Log'!$j:$j, match(1e99, 'Enquiry Log'!$a:$a))
Each of these refers to a column of data extending down in each individual column to the row containing the last date in column A.
Your original relied on individual COUNTA counts to reshape OFFSET. There is no guarantee that there isn't an interim blank row or that they each continue down to the same row. You could homogenize the originals with,
=OFFSET('Enquiry Log'!$J$2, 0, 0, COUNTA('Enquiry Log'!$A:$A), 1)
... but that still doesn't guarantee that interim blank cells in column A wouldn't skew results.

Excel Array Formula, Multiple criteria

I have a table in which multiple weeks of data is stored and I'm trying to return a value based on 2 criteria.
Column A of the data sheet contains the date the report was ran (Always on the same day of the week - 24/05/17, 31/05/17 etc)
I've managed to return the value of column H by using an array formula, based on a cell value (Date) in ''Issues Data Quality Overview'!$B$4' using the following formula:
{=IFERROR(INDEX('Issues Log'!$H$1:$H$20000,SMALL(IF('Issues Data Quality Overview'!$B$4='Issues Log'!$A$1:$A$20000,ROW('Issues Log'!$A$1:$A$20000)-MIN(ROW('Issues Log'!$A$1:$A$20000))+1,""), ROW(A2))),"")}
That returns a value such as "IID-10225-22".
Problem:
Now I need to look up that value in the same table, based on a date in another cell, and return column X. (essentially adding the returned value as a criteria).
In all honesty I'm lost as to how I'd do this.
#Matthew. I understand your formula gives the list of values in column H with column A values matching 'Issues Data Quality Overview'!$B$4 in an ordered list.
Does your Issues Log, column H have multiple occurrence of the same value? (example: IID-10255-22 can have a value in Issues Log, column A that is not the same value as 'Issues Data Quality Overview'!$B$4).
If not, it doesn't make sense to use the result as a lookup value to get column X, you can simply change the code to:
{=IFERROR(INDEX('Issues Log'!$X$1:$X$20000,...}
If it does have multiple occurrences and you want to get the first occurrence of the result in column H and get the value in column X, best to add a formula right next to your array formula and do a VLOOKUP.
I've scrapped the array formula, as it really slowed down the processing speed. Instead I've created a Unique ID (=IssueID&Date) and VLookup'd that.

Google Spreadsheet, SUM or MINUS of above cell in the column using ARRAYFORMULA in the first row

I'm learning to use array formulas and have been successful doing simple things like adding 2 columns together in a third column. For example, I can put =arrayformula(B:B+C:C) in D1 and it adds B and C for each row.
But now I have a situation where I want to subtract two numbers in the same column. I want to take the value of that column in the current row and subtract the previous row's value from it. Without array formulas this is simple: in O7 I put =N7-N6 and cop that down so O8 gets =N8-N7, etc. But that requires copying down every time - can I do the same thing with an array formula?
Basically, can I do something like =arrayformula(B:B+(B-1):(B-1)) ?
Context: column N is a monthly account balance. I would like to calculate how much that balanced changed each month. So for row 7, =N7-N6 gives me that difference. But I'm changing the entire spreadsheet to array formulas so I can stop pasting all of the formulas and I'm stuck on this one since it's comparing the same column.
I'm trying to get everything into Row 1 so my values and calculations can start in Row 2. For example, here's one of my formulas in Row 1:
arrayformula(if(row(A:A)=1,"Total gross income",if(LEN(B:B),B:B+C:C,"")))
Unfortunately, in Column O (the one I asked about originally) if I do this:
=arrayformula(if(row(A:A)=1,"Amount saved this month",if(row(A:A)>1,if(LEN(N:N),N2:N-N:N,""))))
Or this:
=arrayformula(if(row(A:A)=1,"Amount saved this month",if(row(A:A)>1,if(LEN(N:N),offset(N:N,1,0)-N:N,""))))
Every row is off by 1 - the result that should go in Row 3 goes in Row 2, etc. And if I do this:
=arrayformula(if(row(A:A)=1,"Amount saved this month",if(row(A:A)>1,if(LEN(N:N),N:N-offset(N:N,-1,0),""))))
Then it gives me an error because the offset function is trying to evaluate something out of range (possibly it starts with N1 and tries to grab a value 1 row above N1?)
Any advice on how to handle that out-of-range error?
I think the error is because of offset range N:N which starts from N1 and you are trying to shift it -1 or one cell up, which brings the formula out of sheet.
Try this formula instead:
=arrayformula(
{"Amount saved this month";
if(LEN(N2:N),N2:N-offset(N2:N,-1,0),"")})
It uses {} to make an array. See more info:

Bonus. There is no reason to check row number now.

Count If match multiple fields: First field by initials, second field if date has been filled

I'm trying to create a simple tracker. In columns B and C, tasks are tagged with an author, and then the author fills in a completion date.
Above is a dashboard that counts items for easy viewing. I countif for the total, but have not been able write a formula for the complete column. I've tried countifs, but haven't been able to get the formula to work.
Thoughts?
Try below formula as per attached
OUTPUT
Using DSUM will probably send you in the right direction.
http://office.microsoft.com/en-gb/excel-help/dsum-HP005209069.aspx
From what I see in your image, you should do a Pivot table for your dashboard.
If you absoluteley have to (???) get along without a Pivot table, do the following:
start the dashboard in column B, so that column A just contains column header "Tasks" and data (no blank rows allowed!)
count the number of tasks as =COUNTA(A:A)-1 (-1 for the header)
count all other columns as =COUNTA(OFFSET(B5;0;0;$E$2;1)) (in this example you count column B, header is in B4, first data therefore in in B5, number in tasks from above formula in $E$2)
The Offset function basically gives back a range starting relative to a reference and being of chooseable size. So we start it at the first data cell and make it 1 column wide, and #oftasks rows deep
With COUNTIFS, assuming VH is in A8, Tasks/Author/Completed are in Row12 and you have or might have data up to Row1000:
=COUNTIFS(B$12:B$1000,A8,C$12:C$1000,">1")
copied down as required.
You can use SUMPRODUCT to find the amount completed per author.
=SUMPRODUCT(--($B$8:$B$16=A3),--($C$8:$C$16>1))
In this case, the "--" tells SUMPRODUCT to treat each cell in the array (I used the example by User2063626) individually so it starts at the beginning and checks if B8=VH and records the answer as a boolean (1 for TRUE or 0 for FALSE), in this case it does equal VH so it uses a 1. Then it checks to see if C8>1 (it will be if there is a date) and stores a 1. It then multiplies the two values together 1*1=1 to give you a value for the first row. It then moves on and does the check for B9 (gets a 1 because it is equal to VH) and C9 (gets a 0 because there is no date), multiplies the row result 1*0=0 and adds it to the previous result. It repeats for each row in the array and returns the count of rows where the author was VH AND there is a completed date (2).
