Decoupling CRM2.0 for use with ECC6.0
I am looking for some advice regarding decoupling CRM2.0 from the ERP system and using integration software to maintain the process contiuity. We will be upgrading ERP to ECC6. However, the CRM system will not be upgraded. The issue is the BDOCS that reside in CRM2. We really want to speak xml to the integration software from ERP and then talk idoc, bapi or RFC to the CRM 2.0 system. I have been told the CRM2.0 uses BDOCs and am unclear on whether we can call a BDOC inside CRM from an IDOC, BAPI or RFC interface in the Integration Software. Some clarity would be great.
