What is FIFO search strategy in WMS?

SAP FIFO is based on storage type Level.

In warehouse management, search is always executed at storage type level in respective bins. Storage type is a logical destination to store the material in warehouse. Also we defined put away and picking strategies in combination of warehouse and storage type level.

So in FIFO, you have to defined the combination of storage type and warehouse level.

The customization paths for the same are here under;

SPRO 
-> Logistics Execution -> Warehouse Management -> Strategies -> Stock Removal Strategies

In FIFO, the stock removal strategy (First In First Out), the warehouse management system proposes the oldest quant in each storage type from which you want to remove stock.

The system calculates the age of a quant using the date of the goods receipt posting that was set in the quant by the transfer requirement and the transfer order.

Also, for storage type search activation you have to customize:

SPRO 
-> Logistics Execution -> Warehouse Management -> Strategies -> Activate Storage Type Search.
