We presently load the customer hierarchy from our ECC system, but now have a requirement to manually update the customer hierarchy with our non-SAP customers. This manual update was done, but when the next data extract/load from our ECC system, the manual updates that were done were lost. How do we prevent the manual updates to the customer hierarchy from being lost each time we update the customer hierarchy from the ECC system? We are presently running SAP BW 7.4 (without Hana).
