Gap between two tables

Hello, I need compare the two tables each table contains the data of a period 04/2026 and 05/2026, data for I need calculate the entries (new values) and exits (values not more présents),

Is there a function that would allow me to perform this calculation?

thank for your help

Hello Flor,

It looks like the "Keep/remove matching" action can help you with that.

If you apply it in the "Remove matching" mode to one table, you get the new entries. If you apply it to the other table, you get the exits.

You can also try the "Compare tables" action, but it might be less convenient for your purpose.
