You want to perfom a Mass Change for the G/L accounts in the App Manage G/L Account Master Data.
You can select up to 50 G/L accounts for each mass change action.
SAP S/4HANA Cloud
Reproducing the Issue
When you try to perform the Mass change for more than 50 G/L accounts the system does not allow it.
This is a system limitation, more than 50 G/L accounts on Mass change would have performance impacts on the system. (The action process of Mass Change cost less than 3 seconds)
Each Mass Change action for the G/L Accounts that you perform needs to be until 50 G/L accounts each time.
