The IDOC WMBIID01 can be used to send individual storage bins or all storage bins (e.g. an entire aisle) from the external system to the WM system so that they can be blocked or unblocked.

The partner profile input must be maintained for the message type WMBBIN.

On the external system side, it is often not possible to approach certain storage bins or aisles due to technical problems. These storage bins must be blocked so that they are not taken into consideration when the storage bins are determined in the WM system. Blocking of these storage bins must be initiated by the external system. The bins must then be unblocked by the external system when they are ready to be used again.

The IDOC comprises two segments, namely the header data E2LBINH and the item data E2LBINI. The segments are described in the following.

The segment E2LBINH is used to specify whether the storage bins are to be blocked or unblocked. An X must be sent in the field ‘BLOCK’ if the bins are to be blocked and X in the field ‘DEBLO’ if the bins are to be unblocked.

The individual fields in the segment E2LBINI are handled in the same way irrespective of whether the bins are to be blocked or unblocked. The following should be noted with regard to this:

• At least one of the three block indicators ‘SKZUA’, SKZUE’ or ‘SKZSI’ must be sent.

• If a blocking reason is transferred in the field ‘SPGRU’, the associated text must also be maintained in the WM customizing application.

Blocking and unblocking the storage bins from the external system can be simulated in the SAP system. We recommend that the procedures that are relevant for you be tested first in this way. The report RLBBIN00 is available for testing purposes.
