I am trying to create a query based on below requirement. So far I am able to do my query based on single criteria only. Your help would be much appreciated.
1) I have opened a target workbook where I want to fetch matching values for it's two columns (temperature & density) from multiple workbooks saved in a particular folder. Here I am referring to New Query > From file > From Folder option.
2) So In my target work book I have Observed Density and Observed Temperature and now I want to extract volume and weight correction factors from a pool of mutilple workbooks picked in step 1 as mentioned above (all the workbooks in the desired folder not only have Observed Desnity and Observed Temperature but also columns contaning corresponding weight and volume correction factors in them)
That's it. Just want to know if this can be achieved using Power Query or VBA is a must do do get results? If so, any hints would be much appreciated.
I think you are on the right track. I would finish building the Query using the From Folder option to turn the data from all the workbooks into a single dataset. This query does not need to be loaded into an Excel table.
Then I would start a new query based on the 2 columns in your target workbook. They will need to be in a table or named range. In that query you can add a Merge step to match to rows in the From Folder query. Then Expand the results to add the columns you need from the matching rows.

I have a question about how to summarize a list of data, I attached an image of how the data is presented.
The question is how to determine (summarize) the total of activities per unit considering that a person works in 2 units.
You could define that the person working in A / B does 50% of activities for each unit.
As the list of registers is very extensive the idea is to be able to automate, try with a PivotTable and did not give me result.
Any suggestions would be appreciated (xls, sql, etc).

Am really not the best of people when it comes to Pivot Tables, but assuming i know what you are asking for.
1) Add one extra column (dummy) and just put 1 in it, this will be used to sum the number of events that the criteria occurs.
2) Select the whole table and then Insert=>Pivot Tables
3) Click Ok
4) Set Rows (fecha); Values (dummy); and the rest to Filters.
Then you can choose to filter your output the way you want. If you want A and A/B you can select multiple in the filter options.
I have an Excel report that is the output of an opinion tool. In this Excel I have all the responses that the people submit for my quizz, in the questions that are multiple choise answer the tool output those questions like one question per option and only the selected option is the column with data in the Excel. For example, if my quizz is like this:
Q1 Your name:
R1 =
Q2 Options
opt 1
opt 2
opt 3
The Excel report will appear like this
Excel Report
So I want that when I import the Excel to Access it can automatically merge those columns to have only to headers in the Access table: "Q1 Your name:" & "Q2 Options"
Also, for context of the job, I will make some other editions to that imported table and then copy to another Access table (table 2) so even if there is a way to merge those Access columns before copy to the another one I will accept it like, I don't know, insert from this column and if empty insert from that column, I'm not good at doing queries sorry. Only the table 2 will have information, the first table would be like a temporary one so I will daily delete information from that one and preserve the important data en the table 2
Thanks for the support
Simplest way I can see to achieve your goal is to concatenate the three columns; since by the sound of it you will only ever have a value in one column per question per record. You could do this in Excel prior to the import, you could use a calculated field on the table or you could build a query that concatenates all your questions. My suggestion would be Excel since using the =CONCATENATE() function is probably going to be easiest option for you.
If you do import your raw data into Access you will need to assign unique column names, ie Q2_Op1, Q2_Op2, Q2_Op3.
The query syntax to concatenate these fields one would be something like:
SELECT Q1_Name, [Q2_Op1] & [Q2_Op2] & [Q3_Op3] AS Q2_Options
FROM Table1;
Where Q1_Name, Q2_Op1, Q2_Op2, Q3_Op3 are the column names on the imported data table.
I am trying to write a calculated member which acts differently depending on whether the user is filtering by that member or has it dragged down as rows or columns on their pivot table (using Excel).
The rules are:
1. If the user is using the date dimensin as a Report Filter in Excel, then the calculated member should get the maximum date out of all dates that they are filtered by.
2. If they have the date dimension as rows on the pivot table, then I need to apply ClosingPeriod and some other logic.
Please try this. The idea came from here.
Basically the dynamic named set represents what's in the report filters. And the EXISTING keyword trims the list of days down to the filter context of the current cell letting you detect say if one month is on rows. Compare counts and you can detect what the user did.
CREATE HIDDEN DYNAMIC SET CURRENTCUBE.SelectedDays as
[Date].[Date].[Date].Members;
CREATE MEMBER CURRENTCUBE.[Measures].[My Calc] as
CASE
WHEN SelectedDays.Count > {existing [Date].[Date].[Date].Members}.Count
THEN Tail({existing [Date].[Date].[Date].Members},1).Item(0).Item(0).Name
WHEN SelectedDays.Count < [Date].[Date].[Date].Members.Count
THEN Tail(SelectedDays,1).Item(0).Item(0).Name
END
Performance is going to not be good. And I suspect users will be confused with the results of your calc. If you want to describe the business scenario more I can maybe recommend a better approach.
I am working with Excel 2010, Power Query, and PowerPivot.
I have a query named Database that consists of 60+ merged tables containing a total of 2m+ rows. I also have a separate query that consists of two columns PrimaryKey3 and Members (a count of members per month). The entries in PrimaryKey3 are unique, consisting of ID-MMM-YY.
Both queries have PrimaryKey3 in common, however in Database there can be multiple rows with the same PrimaryKey3.
In order to match a member amount to each row in Database, I tried a Left Outer join. There were no errors, but when I try to upload to PowerPivot it says there are only 169K rows. I then tried Full Outer join and Inner Join, and received an error "could not convert value to number," coming from a column already formatted as a text in Database. This column contains numbers and numbers proceeding with a letter: 1234, A234. Every non-blank row has a PrimaryKey3. Why is it trying to reformat my columns/ how do I get around that?
Should I be using a different type of join, or is there another way besides merging to do this?
Hope this makes sense, thank you for any help in advance!
I uploaded both queries to PowerPivot, and created a relationship through PrimaryKey3. I then created a new column in Database with =Related(Enrollment[Members]).
I'm not a vb developer neither so familiar with excel. Anyway i have a project to be done using MS Excel (cannot use access).
System is to provide a ratio analysis(ans some other analysis) of companies where data from an annual report need to entered to the system. Then based on several reports data I can derive graphs and all other information.
My question
Now I can store data in a single sheet like using is as as a database. it'll be like
CompanyName Year Data1 Data2 Data3...
Here the CompanyName can be duplicated as many Years data can be entered. If I use this method Each time I derive company data, I have to search for the relevant rows in the worksheet and keep lots of data in an array as I read through those rows and produce the final result.
Or I can use separate worksheet for each company. Then I only have to search for the relevant sheet name and perform operations in that worksheet it self easily.
So what is the best way to do this?
Thanks
Whatever way works. IMO you could create a defined range (or many) and issue SQL against it just like it was Access table(s). I'm for keeping all like data on the same worksheet even for different companies; but that's just my 2 cents. You can create a pivot to separate out the information and slice/dice it however needed
Since someone liked the comment as an answer:...
It might be simpler to do some of this just using formulas and Excel functions. The basic approach would be to keep the data on one sheet and sort it by year within company so that all the years for a company are grouped together. Then use Filter to create a list of unique companies. These steps get repeated each time you add new data.
Then create 2 formulas for each company: the first uses MATCH to find the first row containing the company name and the second uses COUNTIF to find how many rows there are for the company. Then you can use OFFSET(firstrow,ColumnIndex,NumberOfRows,1) (or similar) to get the required range of data for Charts and ratio analysis etc.
