• What is the cause and solution for SAP error message SDDIC_DDLA_ANNOCHECK059 - Scalar annotation value '&1' not allowed, structured value expected ?

  The SAP error message SDDIC_DDLA_ANNOCHECK059 indicates that there is an issue with the annotation value being used in your data model. Specifically, the error states that a scalar annotation value (like a single value) is not allowed where a structured value (like a complex object or a record) is expected.
  Cause:
  This error typically occurs in the context of SAP's data modeling, particularly when working with annotations in CDS (Core Data Services) views or OData services. The root cause can be one of the following:
  
  Incorrect Annotation Usage: You may have defined an annotation that expects a structured value (like a record or a complex type), but you provided a scalar value (like a string, integer, etc.).
  Mismatched Data Types: The data type of the value you are trying to assign does not match the expected data type defined in the annotation.
  Model Definition Issues: There might be a problem in the way the data model is defined, leading to inconsistencies in how annotations are applied.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Annotation: Check the specific annotation that is causing the error. Ensure that you are using the correct type of value (structured vs. scalar) as per the annotation's definition.
  
  
  Correct the Value: If you are using a scalar value where a structured value is expected, modify your code to provide the appropriate structured value. This may involve creating a new structure or using an existing one that matches the expected format.
  
  
  Check Data Model Definitions: Review the definitions of your CDS views or OData services to ensure that all annotations are correctly defined and that the data types match the expected values.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific annotations you are using. This can provide insights into the expected formats and types.
  
  
  Testing: After making the necessary changes, test your data model or service to ensure that the error is resolved.
