Returns handling in Sales and Distribution (SD) within SAP plays a central role in managing post-sale customer relations when products return for reasons such as defects, wrong shipments, or buyer regrets. In our consulting work, we handle this daily to keep operations running without hitches, update inventory precisely, and adjust finances correctly. This process reverses elements of the initial sales cycle in SD while connecting to Materials Management (MM) and Finance (FI) modules. You encounter it in everyday situations, like a store buyer returning faulty items or a bulk supplier refusing a load that fails to meet specs. It kicks off with recording the return and wraps up with credit issuance, all while maintaining accurate stock. Getting this right aids in fixing project problems where returns affect income reports or storage workflows.
