Use case #1: Transferring external developer code to customer systems Use case #2: Separation of custom developments into logical function groups Use case #3: Separation of SAP systems (carve out, selective company sales) Would you like to restructure and reorganize your developments by introducing namespaces or assigning the objects of the developments to other namespaces? Do you want to restructure your entire company and sell parts of it? Or are you a software house and want to deliver completed SAP solutions and install them safely at the customer? U:R4-REF copies any (partial) sets of your customer objects into the new namespace and automatically adapts all calls in the coding and dictionary. The aim of this tool is to transfer the part of your customer-specific workbench objects specified by you to a different namespace. This happens fully automatically with predefined rules for exceptions and special handling. The complete processing is documented step by step and is therefore available in the system in an audit-proof manner.
