Hi Hayashi,
Please check if the following settings are done in ECC side:
1, activate switch LOG_MM_P2PSE_1
2, create BADI ME_REQ_SOURCING_CUST
IF_EX_ME_REQ_SOURCE_CUST~ACTIVE: Here, 3 output parameters
need to be set to true.
A, when parameter CV_AUT_SOURCING is set to true, external sourcing (e.g. SAP SRM system) is active in SAP ERP system
B, when parameter CV_EXT_RFX_IND is set to true, RFx can be created out of PR directly from SAP ERP system using application CPPR
C, when parameter CV_EXT_SC_IND is set to true, PR in SAP ERP system will be transferred to SAP SRM using application CPPR
B & C should be set as true
Best regards,
Ivy
