SAP Note 16125 - Termination "CONVERT_NO_NUMBER" in KE30, SAPLKEBG

Symptom:

Termination "CONVERT_NO_NUMBER" in SAPLKEBG (RKE_REPORT_INSERT) when you execute a report (transactions KE30 (COPA) or KCR0 (COBPC)).

'"0S001" cannot be interpreted as a number'

Cause and prerequisites

Program RK20+ERKRS (e.g. RK20S00l) was erroneously generated in the customer system (perhaps due to a customer error: import parameter PROGRAM="RK20+ERKRS" entered instead of "RK2O+ERKRS" in function module RKE_GENERATE_ABAP).

Solution
Use transaction SE38 to delete report RK20+ERKRS, e.g. RK20S001,
Caution: Delete report RK20+ERKRS, and NOT Report RK2O+ERKRS (with zero instead of Otto).
Note: If you cannot delete the report with transaction SE38, you can alternatively implement and execute the report below in your system.
