I´m working with Power query excel add in and I´m having a quantity discrepancy between the detailed data and group by results.
I have two queries:
Query 1: “All Systems” that includes all PO lines. Loaded it gives me 662k lines.
Query 2: “Group by” it has the same data (all steps are exactly the same) but at the end I´m removing non necessary columns for faster load and grouping by certain criteria. When I summarize the PO Line count, the total lines is 813k
If I make a deeper analysis, the Group by is only adding lines to a certain "group by" category:

Pivot from Group by Table
Row Labels Sum of PO Lines
Catalog 8665
Free Text 298582
G-Code 284
Material Master 400019
Services 105600
Grand Total 813150

 

Pivot from All Systems
Row Labels Count of PO_Item
Catalog 8665
Free Text 298483
G-Code 283
Material Master 248991
Services 105599
Grand Total 662021

Any idea why the Group by behaves this way? Even if I apply a filter to the data before the grouping, it will bring the same amounts of lines as no filter ever happened. Now that I thinking of it, there is a previous filter applied that might be affecting the only category with discrepancies.

Thank you!

Hi Ileana,

I'm a bit confused because you say there are 662k lines in query 1, which I presume is not grouped, but the grouped query 2 has 813k lines. Surely it would have less lines as it's now grouped?

Are you able to share the file so we can help troubleshoot?

Mynda
