Late Exclusive Material Block (Material Enqueue) for Serial Numbers
Description
As of Release 3.0D, there is a shorter material block (also referred to as material enqueue) for goods movements. However, this block was not active for materials with serial number management. Such materials continued to be blocked exclusively even though the shorter material block was set for the client.
As of Release 3.0E, the late exclusive material block is also possible for materials with serial number management.
