What causes this issue?

You accessed the pull list using a selection type which reexplodes the
bill of materials of the selected orders. In this case, you cannot
stage picking parts.
WM stages picking parts on an order basis and updates the material
staging information in the dependent requirements of order. As, due to
the re-explosion of the BOM, the system determines dependent
requirements dynamically instead of reading them from the database,
this information is not available. The necessary update of the staging
information can also not be carried out when staging picking parts.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Select a selection type for WM material staging where the dependent
requirements are read from the database.
