Cross-System Flow of Goods 

Purpose

The new processes deal with the logistical mapping of goods traffic, particularly with logistics processes in which more than one company code can be involved.

Note, that cross-system flow of goods can only be realized using two-step stock transfers. Stock transfers in one step are not supported.

Standard Scenario

In the standard scenario, we deal with a cross-system stock transfer within a company, that is mapped in the SAP system by stock transport orders and the corresponding deliveries. In the case of deliveries between different company codes, transfer prices can be used

We can differentiate between the following processes:

●     Cross-system stock transfer between profit center nodes, or with a direct change of ownership.

●     Consignment, i.e. stock transfer processes between profit center nodes with subsequent change in ownership when the goods are withdrawn in the receiving profit center node.

●     Cross-system delivery where the goods are delivered to a third party, but the node creating the order and the profit center node are different.

There is also a difference to be made, whether the processes occur within a company code, or across several company codes.

CSL

Cross-system processes can require a cross-system and cross-transaction lock, which was not previously supported by the SAP lock concept. The CSL (cross-system lock) offers a mechanism for enabling this type of lock (see also: Cross-System Lock (BC-CST-EQ)).

When using cross-system flow of goods, several SAP systems (Example: 1 SAP APO, 2 SAP ECC) are used. Using the CSL ensures that as soon as an object is changed, a second application cannot access the same object before the change is complete. This guarantees consistency of data in all involved systems.
