• What is the cause and solution for SAP error message SDDL_PARSER_MSG009 - The annotation name & is used multiple times ?

  The SAP error message SDDL_PARSER_MSG009 indicates that there is a problem with the annotations in your SAP system, specifically that an annotation name is being used multiple times within the same context. This typically occurs in the context of SAP Gateway or OData services where annotations are defined for metadata.
  Cause:
  The error is caused by:
  
  Duplicate annotation names in the metadata definition. This can happen if the same annotation is defined more than once for the same entity or property.
  Incorrectly configured or generated metadata files that include repeated annotations.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Duplicate Annotations:
  
  Review the metadata definition for the entity or property that is causing the error. Look for any repeated annotation names.
  You can use transaction codes like SE80 (Object Navigator) or SE11 (Data Dictionary) to inspect the relevant objects.
  
  
  
  Remove or Rename Duplicates:
  
  If you find duplicate annotations, you will need to either remove the duplicates or rename them to ensure that each annotation name is unique within the context.
  Ensure that the annotations are correctly defined according to the OData standards.
  
  
  
  Regenerate Metadata:
  
  If the annotations are generated automatically (e.g., from a CDS view), you may need to regenerate the metadata. This can often be done by activating the relevant CDS view or service.
  Use transaction SEGW (Gateway Service Builder) to regenerate the service if applicable.
  
  
  
  Check for Custom Implementations:
  
  If you have custom implementations or extensions, ensure that they do not introduce duplicate annotations. Review any custom code or enhancements that may affect the metadata.
  
  
  
  Test the Changes:
  
  After making the necessary changes, test the OData service or application to ensure that the error is resolved and that the annotations are functioning as expected.
