Smart SAP Assistant

• What is the cause and solution for SAP error message REP_EAPS_MSG137 - DataConnector: Loop in &1 line references in SrcID '&2' found ?

  The SAP error message REP_EAPS_MSG137 indicates that there is a loop in the line references in the DataConnector, specifically in the source ID (SrcID) mentioned in the error message. This typically occurs when there are circular references in the data model or configuration, which can lead to infinite loops during data processing.
  Cause:
  
  Circular References: The most common cause of this error is that the data model has circular references. For example, if DataSource A references DataSource B, and DataSource B references DataSource A, this creates a loop.
  Incorrect Configuration: Misconfiguration in the DataConnector settings or in the data model can also lead to this issue.
  Data Mapping Issues: If the mapping of data sources is not set up correctly, it can create unintended loops.
  
  Solution:
  
  Review Data Model: Check the data model for any circular references. Ensure that no DataSource is referencing another in a way that creates a loop.
  Adjust Configuration: If you find any circular references, adjust the configuration to eliminate them. This may involve changing the way data sources are linked or modifying the data flow.
  Check Data Mapping: Review the data mapping settings to ensure that they are correctly set up and do not create loops.
  Testing: After making changes, test the DataConnector again to ensure that the error is resolved.
  Documentation: Refer to SAP documentation or support for specific guidelines on configuring DataConnectors and avoiding circular references.
