Combine two sharepoint lists into one list

(0) ShareShare
ReportReport
Posted on by Nick001 2

Hello all,

 

I would like to make a union over two sharepoint lists so that I can continue working with only one list.

The merging has to be done in Power app, because there is writing to the tables and the total table has to be updated with every change.

The two base tables have the same structure and are each about 50000 rows. Unfortunately, this eliminates the collect function due to its size limitation.

There are no duplicates in the lists so that you could simply merge them. Do you have an idea how I can easily implement this?

Greetings and thanks

    Hi @Nick001 ,

    There is no "Union" function in SharePoint and 100k is way too big for even sequential collections. You may have to query them both with the same query and providing it is Delegable, test for which one is not blank. Writing would be the same (to the one with the record existing).
