• What is the cause and solution for SAP error message FTBU360 - No conversion for rel. category &1 to &2: Cardinalities are inconsistent ?

  The SAP error message FTBU360 indicates that there is an issue with the conversion of a relationship category in the context of data modeling or data transfer, particularly in the context of SAP BW (Business Warehouse) or SAP HANA. The error message suggests that the cardinalities of the relationship categories involved are inconsistent, which means that the expected number of occurrences of one entity does not match the expected number of occurrences of another entity.
  Cause:
  
  Inconsistent Cardinalities: The cardinality settings for the relationship between two entities (e.g., InfoObjects, tables) are not aligned. For example, if one entity is set to allow multiple occurrences (1:N) and the other is set to allow only a single occurrence (1:1), this inconsistency will trigger the error.
  Data Model Changes: Changes made to the data model, such as modifying the relationship between entities or changing the cardinality settings, can lead to this error if not properly managed.
  Data Transfer Issues: When transferring data between different systems or environments, if the cardinality settings are not compatible, this error may occur.
  
  Solution:
  
  
  Check Cardinality Settings: Review the cardinality settings of the relationship between the entities involved. Ensure that they are consistent and correctly defined according to the business logic.
  
  For example, if you have a 1:N relationship, ensure that the corresponding entity is set to accept multiple occurrences.
  
  
  
  Adjust Data Model: If there have been recent changes to the data model, consider reverting those changes or adjusting the relationships to ensure consistency.
  
  
  Data Transfer Configuration: If this error occurs during data transfer, check the configuration settings for the data transfer process. Ensure that the source and target structures are compatible and that the cardinality settings match.
  
  
  Testing: After making adjustments, perform tests to ensure that the error is resolved and that data can be processed without issues.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling cardinality issues in your version of SAP.
