After upgrading to EHP7, while running PC00_M07_CCYR - Processing Year-end Reporting 07 resulted in short dump. In program RPCYERK0, standard class cl_hrpayca_format_string does not exist which has resulted in the error.
Looks like standard class got deleted during the upgrade. Is it due to missing patches by BASIS while upgrading the system. I havent come across this situation during upgrades before.
There's an SAP note 2274111 but SNOTE displayes this as cannot be implemented.
