    Angry Pivot table should show absent for the employee whose presence is not in source data

    I need help for employees attendance report built by pivot table on check in and check out data.
    I have used power query and added some custom columns to calculate Present and Absent employees. Also created calendar and employees list tables in data model and created relationships between tables.
    Please see attachment. Pivot table should show absent for the employee whose presence is not in source data.
    Please help and guide me that what Am I missing?
    Please suggest some Custom Column / Calculated Column / Measure etc for desired result.
    Thanks and regards in advance.

    Hi, I'm no PQ expert but, you could create a cartesian of the Dates + Ees, to generate unique combinations thereof, and then merge that with your raw Table1 {left join}; finally, append resulting table with your Present / Absent calcs, and return to the Model.

    Refer attached for illustration of above [edit: I forgot to add the Absent/Present fields to the Pivot - but you can do this via Pivot window - Table2_2]

    As you infer, there may be a way of doing this using some DAX measure etc, but that's beyond my competency, I'm afraid.

    Excel cannot create what is not in your data. You will need to create some sort of record for those dates that indicates absence. What is not there is not there and cannot be formulated out of thin air. Your records will need to show the Employee for the date but with zeros for data for Excel to find them.

    Alan, the cartesian approach {per previously attached} will auto-generate the 'missing' records - so I think OP should be fine.

    Thanks,

    Cool Re: Pivot table should show absent for the employee whose presence is not in source data

    @alansidman

    Nothing debugged. Power query is tool in excel to use SQL data as source data for Pivot Tables.
    My source data is in SQL. Source data in attached file is just a sample table.

    XLent Point made. I had forgotten about a full cartesian. Like how you did that.

    @Ramzan-ul-Mubarak

    With PQ, you can GetData and select several SQL data bases as your source.

    OP - Original Poster / thread creator

    Please review the attachment provided back in Post #2 as, I believe, this does what you requested; you can review the steps in the PQ code and, hopefully, recreate on your real-life file.

    Question Re: Pivot table should show absent for the employee whose presence is not in source data

    Hey XLent
    When I apply this approach on actual data from SQL and I add custom column (Step 3) and then expand and remove duplicates, excel hangs and dont return to normal.
    It is i think due to large number of data rows. I think Adding custom column adds all dates rows to all employees separately and that increases the number of record lines by hundreds of times.
    One table has 2500 rows and other 25000. I think Adding custom column creates (2,500*25,000=6,25,00,000) rows. Which hangs excel and Power Query dont complte and save.
    What you say?

    Re: Pivot table should show absent for the employee whose presence is not in source data

    @ Ali GW
    I have already said sorry.
    And I apologized for that mistake.
    I think that should be enough. Why are you still following that mistake by me and blaming me again and again?
    If you are administrator and you have some problems with me and cant accept sorry and you dont like new people on the forum (New people can do mistakes) then I request to delete my query and block me from forum (And block any people who do such mistakes).
    If you are so arrogant due to your knowledge and authority (Administration on forum) then please block ordinary people (who have less knowledge) like me.

    Yes, that's correct -- as Alan pointed out earlier, you need a physical record for every Employee and Date for this to appear in your subsequent Pivot.

    You could mitigate the number of permutations initiated in the cartesian join by isolating unique dates beforehand, this would make the 'remove duplicate' step (post-join) redundant.

    So, if you had 2500 EEs in table 2, and 25000 dates in table 1 of which only 1000 are unique you would reduce the cartesian join output to 2.5m (2500 * 1000)

    Obviously, if your Ee list also contains dupes you should remove those first too.

    Refer attached for working version -- again, the other more savvy PQ folk may have other / better ideas.
