• What is the cause and solution for SAP error message HRFORMS670 - Endless loop; MetaNet &1 must not pass data to MetaNet &2 ?

  The SAP error message HRFORMS670, which indicates an "Endless loop; MetaNet &1 must not pass data to MetaNet &2," typically occurs in the context of SAP HR forms or workflows, particularly when there is a misconfiguration in the data flow between different meta networks (MetaNet).
  Cause:
  
  Circular Data Flow: The error suggests that there is a circular reference in the data flow between two meta networks. This means that MetaNet &1 is trying to pass data to MetaNet &2, while at the same time, MetaNet &2 is trying to pass data back to MetaNet &1, creating an endless loop.
  Configuration Issues: Incorrect configuration in the HR forms or workflows can lead to this issue. This could be due to incorrect settings in the form design or the way the meta networks are defined.
  Data Mapping Errors: If the data mapping between the meta networks is not set up correctly, it can lead to this kind of error.
  
  Solution:
  
  Review MetaNet Configurations: Check the configurations of both MetaNet &1 and MetaNet &2. Ensure that they are not set up to pass data to each other in a way that creates a loop.
  Adjust Data Flow: Modify the data flow logic to ensure that one MetaNet does not send data to another in a way that creates a circular reference. You may need to redesign the data flow to break the loop.
  Check Data Mapping: Review the data mapping between the two meta networks. Ensure that the data being passed is necessary and does not create a dependency that leads to an endless loop.
  Testing: After making changes, test the forms or workflows to ensure that the error no longer occurs and that the data flows correctly without creating loops.
