I'm struggling somewhat with a routine to back populate, on a periodic basis, a sharepoint list with data from a lookup on another list
LIST1 has the following fields
UserName UserID UserLocation etc
LIST2 has a various fields but it includes
UserID UserLocation etc
I need to be able to run a routine that if in LIST1 USERLocation field is empty, it will lookup UserLocation based on the matching UserID from LIST2 and patchthe UserLocation to that LIST1 relevant list entry
The list in question is 10000 plus lines long so i come up against collection limits as well.
Is anyone able to suggest a "one off" solution, inside or outside power apps or ideally a push a button based solution for powerapps please?
