Changing ECC Source Systems without Affecting Data Modeling Objects in SAP BW

This document discusses about switching ECC source systems in SAP BW Environment without affecting the data modeling objects in the BW environment. By data modeling objects, we mean transformations, update rules and transfer rules getting inactive or getting deleted. Once the source system is switched, data reload needs to happen to have the initializations and deltas to come from the new source system. Also we have to ensure that the data from old source system( both transactional and master ) needs to be deleted in the BW system before reloading from the data from new source system to ensure consistency in the data from new system.

The below documents will explain the step by step procedure.
