SAP Business ByDesign

1. Go to the Supply Chain Design Master Data Work Center.
2. Navigate to the Locations View.
3. Select the active location as you wish, then you notice that the delete button is grayed out.
4. Choose Edit.
5. Choose Change Status - Set to Obsolete, then the mentioned error would occur.

These are the standard behaviors as designed. 

1. A location can only be deleted when it is in the "In preparation" status.
2. When the Org. structure/unit is activated, the system generates the relevant location and establishes the connection between the business residence and the location, which cannot be obsoleted.

It is not possible to delete or set the location to obsolete. The only solution is to block this location.

[Note] Ensure that all the related logistics tasks are completed before blocking the location.
