SAP help for understanding AUM
Expenditure/income from transfer posting (AUM)
This transaction is used for transfer postings from one material to another if the complete value of the issuing material cannot be
posted to the value of the receiving material. This applies both to materials with standard price control and to materials with moving average price control. Price differences can arise for materials with moving average price if stock levels are negative and the stock value becomes unrealistic as a result of the posting. Transaction AUM can be used irrespective of whether the transfer posting involves a transfer between plants. The expenditure/income is added to the receiving material.
