• What is the cause and solution for SAP error message /PLMI/AL_GSS074 - Mapping of &1 to &2 is not possible; &2 is already mapped ?

  The SAP error message /PLMI/AL_GSS074 Mapping of &1 to &2 is not possible; &2 is already mapped typically occurs in the context of the SAP PLM (Product Lifecycle Management) module, particularly when dealing with the mapping of objects or entities within the system.
  Cause:
  This error indicates that there is an attempt to map one object (represented by &1) to another object (represented by &2), but the target object (&2) is already mapped to a different source object. This situation can arise in various scenarios, such as:
  
  Attempting to create a new mapping for an object that is already associated with another object.
  Trying to reassign a mapping without first removing the existing mapping.
  Data integrity constraints that prevent multiple mappings to the same target object.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check Existing Mappings: Investigate the current mappings for the target object (&2). You can do this by using transaction codes or reports that allow you to view mappings in the PLM module.
  
  
  Remove Existing Mapping: If you find that the target object is already mapped to another source object and you want to change this mapping, you will need to remove the existing mapping first. This can usually be done through the same interface where you manage mappings.
  
  
  Create New Mapping: After removing the existing mapping, you can proceed to create the new mapping from &1 to &2.
  
  
  Consult Documentation: If you are unsure about the mapping process or the implications of changing mappings, refer to the SAP documentation or help resources specific to the PLM module.
  
  
  Check Authorization: Ensure that you have the necessary authorizations to modify mappings in the system. Lack of proper permissions can sometimes lead to unexpected errors.
  
  
  Contact Support: If the issue persists or if you are unable to identify the existing mapping, consider reaching out to your SAP support team or consulting with SAP's customer support for further assistance.
