  Cause:
  The error message is triggered when:
  
  A node in a data flow or expression is being referenced or processed more times than the system allows. This can happen due to:
  
  Circular references in the data flow.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Data Flow/Expression:
  
  Check the logic of the data flow or expression where the error occurred. Look for any circular references or loops that might cause a node to be visited multiple times.

  Verify the configuration settings for the data flow or expression. There may be parameters that limit the number of visits to a node, and you might need to adjust these settings.
  
  
  
  Debugging:
  
  Use debugging tools available in SAP to trace the execution of the data flow or expression. This can help identify where the excessive visits are occurring.
  
  
  
  Consult Documentation:
