Rt now we are working on Decoupling project.I will explain you the scenario .
Client has sap 4.6 C and CRM 2.0 connected with CRM middleware.
Client is upgrading SAP 4.6 C to ECC 6.0 but not upgrading crm2.0 .
Therefore ECC 6.0 will not suport middleware and we need to restore the connection between SAP ecc 6.0 and crm 2.0 without using middleware.
we will be using bdc rfc bapi and idoc and change pointers to establish the connection and restore the data flow.
Can anyone help me if you have some idea i need the bapi or function module that is used for creating products in CRM 2.0 .
