I understand that CRM XIF adapter can be used for communication between SAP CRM & External systems. There are standard IDocs and Function Modules available to create data in CRM as well as send data to external system from CRM.
My question is, if I add few fields to CRM objects e.g. Business partner, can I still use the CRM XIF adapter with the changed object? Can I use CRM XIF IDocs or CRMXIF BAPIs/Function Modules?
Please suggest me ideal & effective way to handle modification to CRM objects as I will be communicating between CRM & external system.
thanks for any help!!!
