Mapping table between CRM bp number and ECC customer number
We are using CRM middleware for customer data replications from ECC to CRM and also for delta download. We have used the mechanism of external number range and internal number range to keep the BP number same in both systems. However SAP does not support this for contact persons data. So we have different numbers for contact persons. But sap keeps track of the mapping and when we update a contact person in one system, it recognises the change and updates in other system. We are writing a custom program to upload few extra info related to a contact persons and the file has the contact person number from ECC. So does any one know what is the table in middleware which has the mapping between contact person number in CRM and ECC ? Or any functuion module ?
