Preparation of LIFO Valuation When you implement LIFO valuation in the system, you generally want to create layers for earlier settlement periods. You have the following options:
If you have previously carried out LIFO valuation in another system, your system administrators can copy the layers from that system to the system.
If you use LIFO valuation for the first time with the system, you can derive the so-called base layer from old stock data in the material master record.
