Stock Identification in the GR and GI Processes 

Purpose

The aim of stock identification is to uniquely identify a stock, that is, a product, with all its stock attributes, such as quantity, batch, or stock type. For example, you receive an inbound delivery with a mixed handling unit (mixed HU). In this case, the HU number is not sufficient for a unique stock identification. When Extended Warehouse Management (EWM) creates warehouse tasks (WTs), it can simultaneously create corresponding stock identifications.

Prerequisites

●     In the Customizing settings for the warehouse process type, you have chosen the stock identification and there you have chosen the default value A (Stock Identification Only if Externally Predetermined) or B (Create Stock Identification if None Exists). For more information, see the Implementation Guide (IMG) for Extended Warehouse Management ® Cross-Process Settings ® Warehouse Task ® Define Warehouse Process Type.

●     You have carried out the prerequisites for Using Stock Identification.

Process

The following figure provides an overview of the use of stock identification in the goods receipt and goods issue processes (GR and GI processes) in a stock transfer between two warehouses.

In this process flow description, the names of the storage bins, the HUs, and so on, serve to provide a better understanding of the above figure. They are, however, merely examples.

       1.      EWM has created an outbound delivery and the corresponding active product WTs in warehouse SPU1.

       2.      You pick stock for the outbound delivery from the storage bins JK01, JK02, and JK03, pack it into HU1, and confirm the active product WTs. When you are picking, you can, if necessary, split the product WTs (see also Stock Identification When Splitting Warehouse Tasks).

       3.      EWM creates an active HU WT so that you can transport HU1 to a packing station. You repack the contents of HU1 into HU2 for the outbound delivery. EWM creates corresponding product WTs that are confirmed immediately for repacking. You can use the stock identification to uniquely select the contents of HU1 that you want to repack. When you are repacking HUs, you can, if necessary, split the stock (see also Stock Identification When Splitting Stock in the GI Process.

       4.      You transport HU2 from pack station WS20 to GI zone WA20. EWM correspondingly creates an active HU WT for this shipment that you then confirm.

       5.      You load HU2 on to the truck and transport it from warehouse SPU1 to warehouse SPU2. EWM creates an active HU WT for loading that you then confirm.

       6.      You receive the inbound delivery containing HU2 in warehouse SPU2. You unload the truck and transport HU2 to GR zone GR10.

EWM creates an inbound delivery and the respective active HU WT that you then confirm. EWM creates different WTs for the GR and GI processes, for example, a putaway WT WTNo.10001 and a pick-WT WTNo.2002. However, EWM creates putaway WTs on the basis of the stock identification of the supplying warehouse, meaning that the stock identification does not change. You do not need to relabel. You can work with the putaway WT as well as selecting the corresponding putaway WT via the stock identification to confirm it in a putaway process. (See also Using Stock Identification).

If you put two different stocks of the same product away, EWM transfers the unique stock identification, in other words each stock has a separate stock identification. You do not have to print new labels. A prerequisite for this is that (in your Customizing settings), you have chosen the default value A (Stock Identification Only if Externally Predetermined) or B (Create Stock Identification if None Exists).

You transport HU2 from the GR zone to deconsolidation station DS10. EWM correspondingly creates an active HU WT for the shipment that you then confirm.

You deconsolidate the contents of HU2 into two new HUs (HU3 and HU4) on the basis of the consolidation group. If necessary, you carry out a WT split. Using the stock identification, you choose the corresponding inactive product WT and confirm the product in a possible destination HU.

       7.      EWM creates corresponding active product WTs while closing the destination HU.

       8.      You transport HU3 and HU4 from the deconsolidation station to the respective final storage bin, in other words, the storage type has the Stor.Ctrl/Put.Compl. indicator, and you confirm the corresponding active product WTs. Here, EWM deletes the stock identification. When you start a new GI process, EWM creates new unique stock identifications.

If you have already picked stock, it might be that you cannot yet post the GI, for example, because the truck has not arrived yet. If you want to put your stock away first, you can carry this out using an ad-hoc WT. EWM does not delete the stock identification from the stock, although EWM has set the indicator for the final storage type. This means that EWM checks whether the stock has another connection to an outbound delivery before the stock identification is deleted. If there is a connection, EWM does not delete the stock identification yet.

Results

You have carried out a GI process and a GR process (stock transfer between two warehouses) with stock identification.
