• What is the cause and solution for SAP error message IN104 - The objects of a link must be different ?

  The SAP error message IN104, which states "The objects of a link must be different," typically occurs in the context of creating or managing links between objects in the SAP system, particularly in the area of Integrated Business Planning (IBP) or other modules that involve object linking.
  Cause:
  This error arises when you attempt to create a link between two objects that are the same or identical. In SAP, links are used to establish relationships between different objects, and the system enforces a rule that prevents linking an object to itself.

  Solution:

  Check Object Selection: Review the objects you are trying to link. Ensure that you are selecting two distinct objects. If you accidentally selected the same object twice, correct your selection.
  
  
  Verify Object Types: Make sure that the objects you are trying to link are of compatible types. Sometimes, linking incompatible object types can also lead to errors.
  
  
  Review Link Logic: If you are using a programmatic approach (like ABAP code or a custom application), ensure that the logic correctly differentiates between the objects being linked.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources for the specific module you are working with to understand the requirements for linking objects.
  
  
  Test with Different Objects: If you are unsure which objects are causing the issue, try linking different pairs of objects to identify the problematic ones.
