Comparing 2 tables - missing info in one table

[romovaro]

hello,

I am having issues comparing 2 tables. 

I hae a column called CUID (is a unique customer number.)

the idea is to compare a Baseline Extract with current data

to know the number of new customer we need to compare current extract vs Baseline. THe idea is to look for CUids included in the current file but are not included in the baseline (cuids don't exist in that file).

WIth current formulas it seems I am only including the ones already existing in both files (= No new cuids)

ANy tip?

Hi,

Could you do this in power query, merger the tables on a anti join to show only records that appear in one?

Another solution in Power Query would be to create a list of the baseline CUIDs and then create a column in the current file that uses List.Contains to look for the current CUID in the baseline list.
