Summary :
Creating or transporting project coding masks in SAP may lead to system failures or termination errors such as RPERF_ILLEGAL_STATEMENT in CJPN_PROJEKTNUMMER_UNEDIT. This issue arises when the input help for projects or WLS elements is accessed if there is a discrepancy between the external numbers and the project coding masks defined in Customizing. It's vital to ensure compatibility between existing project data and new or altered coding masks to prevent inconsistencies and system errors. When transferring masks between systems, key checks are bypassed, potentially leading to conflicts and inconsistencies in the target system.
