Strategy: Addition to Existing Stock 

Use

With this strategy, the system prefers to put away stock in storage bins that already contain stock of the relevant product. A prerequisite for addition to existing stock is that sufficient free capacity still exists in the relevant storage bin. If the system cannot find a storage bin with the same product or if the storage bin does not have sufficient free capacity to store additional quants, the system searches for the next empty storage bin.

This strategy violates the FIFO principle. For this reason, you should only use this strategy in situations where you have insufficient space.

The following figure shows an example of addition to existing stock. You want to put away product AA. Since AA is already occupying a storage bin and free capacity is still available, you can add the product to the existing stock.

Prerequisites

You have made the following settings for the storage type in Customizing for EWM under Master Data  ® Define Storage Type:

·        You have chosen the Standard Warehouse value in the Storage Behavior field.

·        You have chosen the Addition to Existing Stock/Empty Bin value in the Putaway Rules field.

·        You have specified in the Addn.Stock Forbidden field whether or not you want to allow additions to existing stock.

If you want to allow additions to existing stock, choose “ ” (Addition to existing stock permitted) or “M” (Addition to existing stock via addtn ID in product master). If you choose “M”, you must choose the required value for the Addit.to Exist.Stock indicator in the product master.

·        You have chosen a method in the Capacity Check field to activate the capacity check.

·        You have chosen the value 3 in the Mixed Storage field (one HU allowed per bin, in other words, mixed storage is not permitted).
