• What is the cause and solution for SAP error message IQ125 - Serial number &2 for material &1 is in more than one IBase ?

  The SAP error message IQ125 indicates that a specific serial number for a material is associated with more than one Installation Base (IBase). This situation typically arises in scenarios where serial numbers are used to track individual items, and the system expects each serial number to be unique to a single IBase.
  Cause:
  
  Duplicate Serial Number Assignment: The serial number has been assigned to multiple IBase records, which violates the uniqueness constraint.
  Data Entry Errors: Manual entry errors or incorrect data migration can lead to the same serial number being linked to different IBase records.

  Solution:
  
  Identify the Duplicate Entries: Use transaction codes like IQ01 (Create Installation Base) or IQ02 (Change Installation Base) to check the IBases associated with the serial number in question.
  Correct the Data: 
  
  If the serial number is indeed incorrectly assigned to multiple IBases, you will need to determine which assignment is correct and remove the incorrect one.
  You may need to delete or reassign the serial number in one of the IBases.
  
  
  Review Configuration: Ensure that the system is configured correctly to prevent such issues in the future. This may involve checking the settings related to serial number management and IBases.
  Consult Documentation: Refer to SAP documentation or help resources for specific steps on managing serial numbers and IBases.
