• What is the cause and solution for SAP error message B0360 - No conversion for rel. category &1 to &2: Cardinalities are inconsistent ?

  The SAP error message B0360 indicates that there is an issue with the conversion of relational categories in a data model or a query. Specifically, it suggests that the cardinalities (the numerical relationships between entities) are inconsistent, which prevents the system from performing the necessary conversion.
  Cause:
  
  
  Inconsistent Cardinalities: The error typically arises when the cardinality settings between two related entities (e.g., master data and transactional data) do not match. For example, if one entity is defined to have a one-to-many relationship with another, but the other entity is defined with a many-to-one relationship, this inconsistency can trigger the error.
  
  
  Data Model Issues: There may be issues in the data model configuration, such as incorrect settings in the InfoObjects, InfoProviders, or queries that define how data is related.
  
  
  Incorrect Data Types: The data types of the fields being converted may not be compatible, leading to conversion issues.
  
  
  Solution:
  
  
  Check Cardinality Settings: Review the cardinality settings in the data model. Ensure that the relationships between the entities are correctly defined and consistent. For example, if one entity is set to have a one-to-many relationship, the corresponding entity should reflect that relationship accurately.
  
  
  Review Data Model Configuration: Go through the configuration of the InfoObjects, InfoProviders, and any related queries to ensure that they are set up correctly. Look for any discrepancies in the definitions.
  
  
  Data Type Compatibility: Verify that the data types of the fields involved in the conversion are compatible. If necessary, adjust the data types to ensure they can be converted without issues.
  
  
  Check for Updates or Notes: Sometimes, SAP releases notes or updates that address specific issues. Check the SAP Support Portal for any relevant notes that might provide additional guidance or fixes.
  
  
  Testing: After making changes, test the data model or query to ensure that the error has been resolved.
