Goods movements are processed by the WMS without exception via one- or two-stage transfer orders. According to the one-step method it is immediately acknowledged after the transfer order has been created. In the case of two-stage processing the times of creation and acknowledgment differ indefinitely.
To flexibly map transport chains, the software creates a separate transport order for the source storage bin and the destination bin. To allocate stocks to the receipt storage bin and to reserve to the issue storage bin, the system uses two separate stock accounts.
In the case of two-step processing, resource management activates the transport orders. In addition the WMS differentiates between goods management transport orders (for example, order picking or goods issue) and transfer orders from the material flow calculator.
