When addition to existing stock has been defined as a putaway strategy for a storage type, the system places goods in storage bins that already contain the same material. With this strategy, the system searches for a storage bin in which the material is already being stored. A prerequisite for addition to existing stock is that sufficient capacity still exists in the respective storage bin. If the system cannot find a storage bin with the same material or the capacity of the storage bin will not allow additional quants to be stored, the system switches to the "next empty bin" strategy, that is, it searches for the next available empty storage bin.

The FIFO principle is violated with this strategy; therefore, you should use this strategy when warehouse space is limited.

The strategy for adding to existing stock is illustrated below.

There are two ways to define addition to existing stock.

• You use the "addition to existing stock" placement strategy for the storage type.

• Set the additional stock indicator (Addn to Stock) in the storage type record itself. To change the storage type, see the appropriate section on defining a storage type under Master data  in the Warehouse Management IMG documentation.
