Delivery &1 originates from another system - split not possible. &4

What causes this issue?

Outbound delivery &V1& comes from another system. It was created in an
SAP S/4HANA system and distributed to this Warehouse Management (WM)
system.

System Response

A split cannot be permitted in decentralized WM systems unless you can
guarantee that the deliveries are not packed in the SAP S/4HANA system.
The system cannot make this check automatically. The outbound delivery
split cannot be carried out in decentralized WM systems until you make
system settings that delete packing in the SAP S/4HANA following
distribution.

How to fix this error?

The system administrator can set an indicator in the Implementation
Guide that deletes any packing in the delivery in the SAP S/4HANA system
during distribution, which makes the subsequent outbound-delivery split
possible in decentralized WM systems.

Procedure for System Administrators

Set the
<DS:DE.LESHP_ALLOW_DECENTRAL_SPLIT>Allow delivery split</> indicator in
the
<DS:BOOK.SIMG_LEIDW>Decentralized WMS Integration</> section in both
the
<DS:SIMG.SIMG_XXLEIDWDSPALLOW>SAP S/4HANA system</> and the
<DS:SIMG.SIMG_XXLEIDWDSPLOCK>WM system</>. You must also set this
indicator in the SAP S/4HANA system if you have more than one WM system
in use, but do not want to use the delivery split in all of them.
