Error GMMASTERDATA225

Hi,

We are getting "Budget validity time slice 020 cannot be changed after budget is assigned" error when trying to extend budget validity dates in a grant. We are upgrading to ECC EhP7 with SAP_APPL at SAPKH61708 and EA-PS at SAPK-61708INEAPS.

This error doesnt pop up in our current EhP4 systems. How can I mitigate and change the budget validity dates without an error?

Thanks for your help.

Regards,

Nathan
