  The SAP error message VMP_MSG132 indicates that an action cannot be performed because a sub-assembly cannot be reassigned. This error typically occurs in the context of production planning and control, particularly when dealing with production orders, sub-assemblies, or components in a manufacturing environment.
  Cause:
  The error can arise due to several reasons, including:
