• What is the cause and solution for SAP error message IB_DECO137 - Serial number &2 for material &1 is already assigned to an installed base ?

  The SAP error message IB_DECO137 indicates that a specific serial number for a material is already assigned to an installed base. This typically occurs in the context of SAP's Installed Base (IB) management, where serial numbers are used to track individual items or components.
  Cause:
  The error arises when you attempt to assign a serial number to an installed base that is already linked to another installed base or has been previously assigned. This can happen due to:
  
  Duplicate Assignment: The serial number has already been assigned to a different installed base.

  Solution:
  To resolve this error, you can take the following steps:

  Verify the status of the serial number in the system.
  
  
  
  Correct the Assignment:
  
  If the serial number is indeed assigned to another installed base and you need to reassign it, you may need to unassign it from the current installed base first. This can be done using transaction codes like IB02 (Change Installed Base) or IB03 (Display Installed Base).
  Ensure that the serial number is not in use before attempting to reassign it.
  
  
  
  Data Validation:
