• What is the cause and solution for SAP error message IQ129 - Equipment &1 is already assigned to an IBase ?

  The SAP error message IQ129 indicates that the equipment you are trying to assign is already linked to an Installation Base (IBase). This typically occurs in the context of SAP's Customer Service (CS) or Plant Maintenance (PM) modules, where equipment is managed and tracked.
  Cause:
  The error arises when you attempt to assign an equipment number to an IBase that is already associated with another IBase or when the equipment is already linked to an existing IBase. This can happen due to:
  
  Duplicate Assignment: The equipment is already assigned to a different IBase.
