Find mismatch amount values in two two table

[oadewuyi]

Hello all,

I am working on a report that's basically dealing with comparison of values from an old legacy system with the new Mongo DB platform. There are about 11k records and the expected output is that values on both sides should match using the unique ID for each user records.

Some values did not match(about 2k records) and I want to be able to display those records without searching through the entire tables.

Anyone with ideas or solutions on how to achieve this will be greatly appreciated.

Hi,

Please check the below picture and the attached pbix file.

It is for creating a new table that shows unmateched IDs with values.

New Table displays ID with unmatched values =
FILTER (
    Old,
    Old[Value1]
        - MAXX ( FILTER ( New, New[ID] = EARLIER ( Old[ID] ) ), New[Value1] ) <> 0
        && Old[Value2]
            - MAXX ( FILTER ( New, New[ID] = EARLIER ( Old[ID] ) ), New[Value2] ) <> 0
        && Old[Value3]
            - MAXX ( FILTER ( New, New[ID] = EARLIER ( Old[ID] ) ), New[Value3] ) <> 0
)

@oadewuyi , Try a new table in DAX , and see if that can help

table = except('OLD DB', 'New DB')
