Batch Update Lines

I’m trying to check whether I still have any Division not assigned.

For example, I go into Payments, then Batch Update, and I select all entries in order to copy them and paste them into Excel. However, I get the following error:

Internal Error
Manager 26.5.12.3588
System.IO.InvalidDataException: Form value count limit 1024 exceeded.

I understand that it can only handle up to 1024 lines, but how can I proceed if there are more than 1024 lines?
