SAP SRM IDOC'S BDOC'S and BAPI'S clarification
please clarify the following points:
1) For a particular object say Shopping cart, how to asscertain whether it uses IDOC, BDOC, BAPI. Is there any defined process/method to know which mode of transfer to the other system i.e backend.
2) Are BDOC'S relevant only to SAP CRM or for SAP SRM also.
maximum points would be rewarded.
