• What is the cause and solution for SAP error message IW137 - No relationships possible for sub-operations ?

  The SAP error message IW137 ("No relationships possible for sub-operations") typically occurs in the context of maintenance orders or production orders when there is an attempt to create or manage relationships between operations or sub-operations in a routing or work order. This error indicates that the system cannot establish a valid relationship between the specified operations or sub-operations.
  Causes:
  
  Incorrect Operation Sequence: The operations may not be sequenced correctly, or the dependencies between them are not defined properly.
  Missing Relationships: There may be no defined relationships (like start-to-start, finish-to-start) between the operations or sub-operations.
  Invalid Operation Types: The types of operations being linked may not be compatible.
  Configuration Issues: There may be issues with the configuration of the routing or work order that prevent the establishment of relationships.

  Solutions:
  
  Check Operation Sequence: Review the sequence of operations in the routing or work order. Ensure that they are logically ordered and that the relationships make sense.
  Define Relationships: If relationships are missing, you may need to define them in the routing or work order. This can be done in the routing transaction (e.g., CA01, CA02) or in the order itself (e.g., IW31, IW32).
  Review Operation Types: Ensure that the operations you are trying to link are of compatible types and that they can logically be related.
  Configuration Review: Check the configuration settings in the system related to routing and operations. Ensure that all necessary settings are correctly defined.
  Data Validation: Validate the master data for the operations involved. Ensure that all required fields are filled and that there are no inconsistencies.
