• What is the cause and solution for SAP error message /SCMTMS/VSS_ABAP_ENG003 - Inconsistent input: cycle in activity graph ?

  The SAP error message /SCMTMS/VSS_ABAP_ENG003 Inconsistent input: cycle in activity graph typically occurs in the context of SAP Transportation Management (TM) when there is a cycle detected in the activity graph of a transportation process. This can happen during planning or execution when the system tries to process a sequence of activities that leads back to a previous state, creating a loop.
  Cause:
  
  
  Cycle in Activity Graph: The most common cause is that the configuration or the data entered for the transportation process has created a circular dependency. This can happen if:
  
  Activities are incorrectly linked.
  There are overlapping or conflicting routes or activities.
  The sequence of activities defined in the transportation process is not linear and leads back to a previous activity.
  
  
  
  Incorrect Configuration: Misconfiguration in the transportation lanes, routes, or activities can lead to cycles being formed.
  
  
  Data Integrity Issues: Inconsistent or incorrect data entries in the master data (like transportation lanes, routes, or activities) can also lead to this error.
  
  
  Solution:
  
  
  Review Activity Graph: Check the activity graph for the transportation process to identify any cycles. You can do this by:
  
  Analyzing the sequence of activities defined in the transportation process.
  Ensuring that there are no activities that point back to a previous activity.
  
  
  
  Correct Configuration: If you find any cycles, you will need to correct the configuration:
  
  Adjust the sequence of activities to ensure a linear flow.
  Remove or modify any overlapping routes or activities that may be causing the cycle.
  
  
  
  Data Validation: Validate the master data related to transportation:
  
  Ensure that all transportation lanes, routes, and activities are correctly defined and do not create circular dependencies.
  Check for any inconsistencies in the data that could lead to this error.
  
  
  
  Testing: After making changes, test the transportation process again to ensure that the error does not occur.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to transportation management for any specific guidelines or updates that may address this issue.
