• What is the cause and solution for SAP error message SADL_GW_ATC_VOCAN053 - For Property Path: '&1' only association cardinality 1 allowed ?

  The SAP error message SADL_GW_ATC_VOCAN053 typically occurs in the context of SAP Gateway and the SAP ABAP programming environment, particularly when working with the SAP Data Access Layer (SADL). This error indicates that there is an issue with the cardinality of an association in your data model.
  Cause:
  The error message states that for the specified property path, only an association with cardinality 1 is allowed. This means that the system expects a one-to-one relationship between the entities involved in the association, but the current configuration or usage suggests that there might be a one-to-many or many-to-many relationship.
  Common Causes:
  
  Incorrect Association Definition: The association in the data model may be defined with a cardinality that does not match the expected cardinality in the context where it is being used.
  Data Model Misconfiguration: The underlying data model may have been incorrectly set up, leading to mismatches in expected relationships.
  Query or Service Definition Issues: The way the query or service is defined may be attempting to access the association in a way that is not compatible with its cardinality.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Association Definition:
  
  Review the definition of the association in your data model. Ensure that it is defined with the correct cardinality (1:1) as expected by the context in which it is being used.
  
  
  
  Adjust Data Model:
  
  If the association is indeed meant to be one-to-many or many-to-many, you may need to redefine the association and adjust the related entities accordingly.
  
  
  
  Review Query Logic:
  
  If you are using a query or service that accesses this association, ensure that the logic aligns with the defined cardinality. For example, if you are trying to retrieve multiple records where only one is expected, you may need to adjust your query.
  
  
  
  Test Changes:
  
  After making adjustments, test the changes to ensure that the error no longer occurs and that the expected data is returned.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or community forums for additional guidance on handling associations and cardinalities in your specific version of SAP.
