  The SAP error message IQ150 indicates that a functional location is already assigned to an installed base. This typically occurs in the context of SAP's Plant Maintenance (PM) or Customer Service (CS) modules, where functional locations are used to represent physical locations or equipment within a plant or service environment.
  Cause:
  The error arises when you attempt to assign a functional location to an installed base that is already linked to another installed base. This can happen due to:

  Verify if the functional location is indeed assigned to another installed base.
