Hi Gurus, I'm trying to transfer a few business partners within CRM server using: Basic type: CRMXIF_PARTNER_REL_SAVE_M02 Message Type CRMXIF_PARTNER_REL_SAVE_M In a few of the BP IDocs I get the error (Status 51) saying "Function 27 does not exist". Can you throw any light on this? Thanks & Regards, Rahul
