Summary :
User exits EXIT_SAPLNIW1_001 (>= Release 4.6B) and EXIT_SAPLNIWE_001 (<= Release 4.5B) are missing caller program information in their input parameters, affecting the function of calculating the lowest value procedures from RMNIWE10 and RMNIWE20 programs. This note suggests enhancing the interface by adding the import parameter I_NIWEX to capture necessary details. For Release >= 4.6B, add I_NIWEX with TYPE specification and a reference type MY_NIWEX. For Release <= 4.5B, include I_NIWEX with a reference to SNIWE_NIWEX. Subsequent modifications in the source code are required to implement these changes.
