Summary :
This SAP Note provides guidance for issuing custom error messages in transactions ME21N and ME51N for purchase orders and requisitions. By using the enhancement MM06E005 with function exit EXIT_SAPMM06E_012, users can generate messages directed to specific business objects and fields, utilizing macros mmpur_business_obj_id, mmpur_metafield, and mmp omessage_forced for linking these messages. The enhancement ensures proper error signaling and cursor positioning on relevant UI fields. For purchase requisitions, the MEREQ001 enhancement should be used with user exits EXIT_SAPLMEREQ_005 and EXIT_SAPLMEREQ_010 for effective message handling. The instructions include utilizations of macros for systematic issue handling and require implementation of corrections in Include LXM06TAP and ZXM06U43 for complete setup.
