• What is the cause and solution for SAP error message SDDIC_DDLA_ANNOCHECK010 - Only one enum value allowed for annotation '&1' ?

  The SAP error message SDDIC_DDLA_ANNOCHECK010 indicates that there is an issue with the annotations in your data model, specifically that only one enumeration value is allowed for a certain annotation, but multiple values have been provided.
  Cause:
  This error typically arises in the context of SAP's ABAP programming or when working with the SAP Gateway and OData services. The specific cause of the error is that an annotation is defined in a way that it expects a single value (for example, a single enumeration), but the code or metadata is providing multiple values. This can happen due to:
  
  Incorrect Annotation Definition: The annotation might be defined incorrectly in the metadata or in the ABAP code.
  Multiple Values Provided: The code might be attempting to assign multiple values to an annotation that only allows one.
  Version Mismatch: There could be a mismatch between the expected version of the OData service and the actual implementation.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Annotation Definition: Review the annotation definition in your ABAP code or metadata. Ensure that it is defined correctly and that it only specifies a single value where required.
  
  
  Modify Code: If your code is attempting to set multiple values for an annotation that only allows one, modify the code to ensure that only a single value is assigned.
  
  
  Review OData Service: If you are working with an OData service, check the service definition and ensure that it aligns with the expected annotations. You may need to regenerate the service or update the service definition.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific annotations you are using. This can provide insights into the expected values and how to properly define them.
  
  
  Testing: After making changes, test the application or service to ensure that the error is resolved.
