• What is the cause and solution for SAP error message SDDIC_DDLA_ANNOCHECK061 - Annotation value '&1' must not be an array type. Expected type of '&2' ?

  The SAP error message SDDIC_DDLA_ANNOCHECK061 indicates that there is an issue with the annotation value in your ABAP code or data model. Specifically, it states that the annotation value you are trying to use is of an array type, but the expected type is something else (as indicated by &2 in the message).
  Cause:
  This error typically occurs in the context of annotations in ABAP CDS (Core Data Services) views or when working with OData services. The root cause can be one of the following:
  
  Incorrect Annotation Usage: You may be using an annotation that expects a single value, but you are providing an array (multiple values).
  Data Model Mismatch: The data model or the structure of the entity you are working with may not align with the expected types defined in the annotations.
  Type Definition Issues: The type definitions in your CDS view or data model may not be correctly defined, leading to a mismatch between expected and provided types.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Annotation: Check the specific annotation you are using and ensure that it is intended to accept a single value rather than an array. Refer to the SAP documentation for the correct usage of the annotation.
  
  
  Check Data Types: Verify the data types of the fields in your CDS view or data model. Ensure that the field you are annotating is of the expected type and not an array.
  
  
  Modify the Code: If you are inadvertently passing an array, modify your code to pass a single value instead. For example, if you are using a collection, ensure you are accessing a single element rather than the entire collection.
  
  
  Test Changes: After making the necessary changes, test your CDS view or OData service to ensure that the error is resolved.
  
  
  Related Information:
