I have a question regarding Power Query and Tables as parameters for excel.
Right now I can create a table and use it as a parameter for Power query via Drill down.
But I'm unsure how i would proceed with a Table that has multiple values. How can a table be recognized with multiple "values" as a parameter
For example:
I have the following rawdata and parameter tables
Rawdata+parametertables
Now if I wanted to filter after Value2 with a parameter tables I would do a drill down of the parameter tables and load them to excel.
After that I have two tables that I can filter Value2 with an OR Function by 1 and 2
Is it possible to somehow combine this into 1 Table and that it still uses an OR Function to search
Value2
Im asking because I want it to be potentially possible to just add more and more parameters into the table without creating a new table everytime. Basically just copy paste some parameters into the parameter table and be done with it
Thanks for any help in advance
Assuming, you use Parameters only for filtering. There are other ways, but this one looks the best from performance point of view.
You may create Parameters table, so you have such tables:
Note, it's handy to have the same names (Value2) for key column in both tables, otherwise Table.Join will create additional column(s) after merging tables.
Add similar step to filter RawData table:
join = Table.Join(RawData, "Value2", Parameters, "Value2")

How to get data from 2 columns, in different tables within Excel Power Query, to sum into 1 column?
For example: Table names - Main_Company_HR_Data and Company1_HR_Data -- Fields I want to combine: Main_Company_HR_Data.Gross Company1_HR_Data.Gross.
Within the Data Model; I have established the connection to my data warehouse, and have linked the tables in Power Query as well. I added a column and attempted several suggestions from multiple sites. None work. I have been using: Calculate(SUMX(Main_Company_HR_Data.Gross))+ SUMX(Company1_HR_Data.Gross). And other iterations of the sort, and it doesn't work.
I had this issue, and the way I tackle it, is to make it as simple as possible.
Try this:
Enter this code as a formula, adding a column, in the tab which will have the field summed.
=LOOKUPVALUE('Company1_HR_Data'[Gross],'Company1_HR_Data'[Unique_ID],'Main_Company_HR_Data'[Unique_ID])
Create a column to sum the two in the same tab you created the above formula.
='Main_Company_HR_Data'[Gross]+'Company1_HR Data'[Gross]
I have two tables that use a unique concatenated column for their relationship. I simply want to make a measure that uses the values from C4 of Table1. I thought I could use a simple formula like =values(Table1[C4]) but I get an error of "A table of multiple values was supplied where a single value was expected."
Side note: I realize the concatenation is unnecessary here in this simple example, but it is necessary in the full data I am working with which is why I added it into this example.
Here's a simplified set of tables for what I am trying to do:
Table1
Table2
Relationships
First you should think. Do I really need a Calculated column? Can't this be calculated at runtime?
But if you still want to do it, you can use RELATED or RELATEDTABLE.
Keep in mind if you are pulling from RELATEDTABLE, returns many values. So you should apply some type of aggregation like SUMX or MAXX.
You can use context transition to retrieve the value.
= CALCULATE(MAX(Table1[C4])
Please see the code below for a Power BI table in DAX:
TABLE1 =
VAR ParticipantOneParticipantId =
SELECTEDVALUE(
ParticipantOneDetails[ParticipantId]
)
RETURN
FILTER(
ParticipantOneMeetings,
ParticipantOneMeetings[ParticipantId] = ParticipantOneParticipantId
)
I am fetching a value for ParticipantId from a sliced table called ParticipantOneDetails and setting ParticipantOneParticipantId to it.
In the next step I am trying to filter the table ParticipantOneMeetings based on its column ParticipantId comparing it against ParticipantOneParticipantId.
The problem is that the resulting table is coming out empty even though I know that ParticipantOneParticipantId must have a value and the ParticipantOneMeetings table also has values. I verified by comparing against a hard-coded string.
Can you please point out what I am doing wrong? Is comparing this way not legal?
The problem lies in the process you are trying. A calculated/custom tables and columns are static. They always refresh when the data set is refreshed. They do not interact dynamically with the slicer value. So it is impossible to get data from a slicer dynamically for a Custom Table generation.
Now, your requirement of creating a new table based on slicer value is not completely clear to me. As what you are trying, is a simple filtered output of your table "ParticipantOneMeetings" after applying the Slicer. If you have relation between your 2 tables using column "ParticipantId", change in Slicer will automatically filter out values in ParticipantOneMeetings table. Why you wants to hold this same filtered values in a new Custom table is really a mater here to know for finding appropriate solution for you.
Turns out I needed to add the following measure to the table output:
MeetingsAttendedByBothParticipants =
countrows(
INTERSECT(
VALUES(ParticipantOneMeetings[Name]),
VALUES(ParticipantTwoMeetings[Name])
)
)
The above provides an intersection on output of two sliced meeting tables. This results in a list of meetings that both persons attend.
I have a VBA script that generates a query string for a SAP HANA ODBC Connection in Excel. The query is determined by user inputs and can vary greatly in length. The query itself uses many versions of a similar query appended to one another using UNION ALL syntax.
The script sometimes throws a runtime error when trying to refresh. From my research, it has become clear that the reason for this is that the CommandText string exceeds a maximum allowed length of 32,767 (https://ask.sqlservercentral.com/questions/50819/too-long-sql-in-excel-vba.html).
I wondered whether there is a workaround for this, other than using a stored procedure (I am not against this if there is a way to create a stored procedure at runtime then execute it, but I cannot use a predefined stored procedure as my query is always different hence the need for VBA to create it)
Some more info about the dynamic query in VBA:
Column names, as well as parameters, are created dynamically and can be different every time
The query uses groups of lists of product numbers to generate an IN statement for each product group, then sums the sales for those products under the name of the group. These are then all UNION'd together to create one table with grouped records
Example of user input:
Example of resulting query:
WITH SOME_CTE (SOME_FIELDS) AS
(SELECT SOME_STUFF
FROM SOME_TABLE
WHERE SOME_STUFF_IS_GOING_ON)
SELECT GEND "Gender", 'Attribute 1' "Attribute", SUM(UNITS) "Units", SUM(VAL) "Value", SUM(MARGIN) "Margin"
FROM SOME_CTE
WHERE PRODUCT IN ('12345', '23456', '34567', '45678')
GROUP BY GEND
UNION ALL
SELECT GEND, 'Attribute 2' ATTR_NAME, SUM(UNITS), SUM(VAL), SUM(MARGIN)
FROM SOME_CTE
WHERE PRODUCT IN ('01234', '02345', '03456', '03567')
GROUP BY GEND
ORDER BY "Gender", "Attribute"
...and so on.
As you can see, with 2 attribute groups containing 4 products each there is no problem, but when we get to about 30 with several hundred each, it could be too long.
Note: I have tried things like shortening field references in the repeated parts of the query string to 1 character etc. which helps but does not solve the problem.
Any help would be greatly appreciated.
One workaround is to send multiple queries. Since you are using union all, you could execute every time single select statement, i.e.
create table in (for example) master database (don't create temporary tables! as they will be dropped after every query) - but before that, make sure you create new table, so delete old one if exists (also drop the table after you are done with it). Now every single select statement you'll change to insert statement, which will insert records to your so-called temporary table.
This way, you'll avoid lengthy queries, you'll just send single insert .. into.. select statements.
At the end, to get all results, you just need simple select query. After getting this data, you should drop that table, as it's no longer needed.
Due to performance issues I need to remove a few distinct counts on my DAX. However, I have a particular scenario and I can't figure out how to do it.
As example, let's say one or more restaurants can be hired at one or more feasts and prepare one or more menus (see data below).
I want a PowerPivot table that shows in how many feasts each restaurant was present (see table below). I achieved this by using distinctcount.
Why not precalculating this on Power Query? The real data I have is a bit more complex (more ID columns) and in order to be able to pivot the data I would have to calculate thousands of possible combinations.
I tried adding to my model a Feast dimensional table (on the example this would only be 1 column of 2 rows). I was hoping to use that relationship to be able to make a straight count, but I haven't been able to come up with the right DAX to do so.
You could use COUNTROWS() combined with VALUES().
Specifically, COUNTROWS() will give you the count of rows in a table. That means COUNTROWS is expecting a table is input. Here's the magic part: VALUES() will return a table as results, and the table it returns are the distinct values in the table/column that you provide as the argument for VALUES().
I'm not sure if I'm explaining it well, so for the sample data you provided, the measure would look like this (assuming the table is named Table1):
Unique Feasts:=COUNTROWS(VALUES('Table1'[Feast Id]))
You can then create a pivot table from Powerpivot, and drag Restaurant Id into Rows, and drag the measure above into Values. Same result as DISTINCTCOUNT, but with less performance overhead (I think).
