Which transaction code is used to record the return of items back to the source of supply?

The transaction code used to record the return of items back to the source of supply is RTL. This code specifically designates the process for returning inventory items, which is crucial for maintaining accurate inventory records and managing stock levels effectively. The RTL transaction allows for a systematic approach to handle returns, ensuring that data reflects the movement of goods and that supplies can be replenished as necessary.

In logistics and supply chain management, accurately recording returns helps in analyzing inventory usage and assessing supplier performance. By using the appropriate transaction code, personnel can ensure that returns are processed efficiently, reducing discrepancies and maintaining a streamlined supply chain. This is particularly important for operational efficiency and financial tracking within supply and logistics management systems.
