• What is the cause and solution for SAP error message RODPS_REPL531 - Selection &1 is not Cartesian (has holes or concave corners) ?

  The SAP error message RODPS_REPL531 indicates that there is an issue with the selection set used in a data replication process, specifically that the selection is not Cartesian. This means that the selection set has "holes" or "concave corners," which can occur when the data being selected does not form a complete grid or when there are gaps in the data.
  Cause:
  
  Data Gaps: The selection set may have missing values or ranges that create gaps in the data.
  Non-Uniform Data: The data may not be uniformly distributed, leading to concave shapes in the selection.
  Incorrect Selection Criteria: The criteria used to define the selection set may be incorrectly specified, leading to an invalid selection.
  
  Solution:
  
  Review Selection Criteria: Check the selection criteria used in the data replication process. Ensure that the criteria are correctly defined and do not create gaps in the selection.
  Adjust Data Ranges: If the selection involves ranges, ensure that they are continuous and do not leave any gaps. For example, if you are selecting a range of dates, ensure that all dates are included without missing any.
  Use Complete Data Sets: If possible, use a complete data set that does not have any missing values or gaps. This may involve adjusting the source data or the way it is being queried.
  Test with Smaller Sets: If the issue persists, try testing with smaller or simpler selection sets to identify where the problem lies.
  
  Related Information:

  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and what solutions they have found.

  By addressing the selection criteria and ensuring that the data is continuous and complete, you should be able to resolve the RODPS_REPL531 error.
