• What is the cause and solution for SAP error message /SCTM/RG022 - Means of transport &1 is contained twice in hierarchy (cycle) ?

  The SAP error message /SCTM/RG022 Means of transport &1 is contained twice in hierarchy (cycle) typically occurs in the context of SAP Transportation Management (TM) when there is a cyclic reference in the hierarchy of means of transport. This means that the system has detected that a specific means of transport is being referenced more than once in a way that creates a loop or cycle, which is not allowed.
  Cause:
  
  Duplicate Entries: The means of transport has been defined multiple times in the hierarchy, leading to a situation where the system cannot determine a clear path.
  Incorrect Hierarchical Structure: The configuration of the means of transport hierarchy may have been set up incorrectly, causing a cycle.
  Data Migration Issues: If data was migrated from another system, it may have introduced duplicates or cycles in the hierarchy.
  
  Solution:
  
  
  Check Hierarchy Configuration:
  
  Navigate to the means of transport configuration in SAP TM.
  Review the hierarchy to identify any duplicate entries or cycles.
  Ensure that each means of transport is uniquely defined and does not reference itself or create a loop.
  
  
  
  Remove Duplicates:
  
  If duplicates are found, remove or consolidate them to ensure that each means of transport is only defined once in the hierarchy.
  
  
  
  Validate Data:
  
  If the data was migrated, perform a validation check to ensure that the hierarchy is correct and does not contain any cycles.
  Use transaction codes like /SCTM/TO or relevant configuration transactions to review and adjust the means of transport settings.
  
  
  
  Testing:
  
  After making changes, test the configuration to ensure that the error no longer occurs and that the means of transport can be used as intended.
