SAP Error Message - Details

• Message type: E = Error

• Message class: MD - Material Requirements Planning (MRP)

• Message number: 511

• Message text: Could not explode phantom assembly &1

What causes this issue?

The system could not explode one or more phantom assemblies when
exploding the order BOM.
Although there are BOMs for these phantom assemblies, no valid BOMs
could be selected that correspond to the selection criteria.

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

System Response

The system could not determine any components for the relevant phantom
assemblies when exploding the BOM.
However, the system created dependent requirements with the
property "Phantom Assembly" (DUMPS = 'X') for these assemblies.

How to fix this error?

Check the selection criteria and the BOM validities for the phantom
assemblies.
