• What is the cause and solution for SAP error message SDDIC_DDLA_ANNOCHECK011 - Annotation '&1' must be an array type ?

  The SAP error message SDDIC_DDLA_ANNOCHECK011 indicates that there is an issue with an annotation in your ABAP code or data model. Specifically, the error message states that the annotation &1 must be an array type. This typically occurs when an annotation that is expected to be an array (a collection of values) is defined or used incorrectly as a single value.
  Cause
  The error can occur due to several reasons:
  
  Incorrect Annotation Definition: The annotation is defined in a way that it expects an array but is provided with a single value.
  Data Model Mismatch: The data model or structure being used does not match the expected format for the annotation.
  Code Implementation Error: The code that utilizes the annotation may not be correctly handling the expected array type.
  
  Solution
  To resolve this error, you can take the following steps:
  
  
  Check Annotation Definition: Review the definition of the annotation in your ABAP code or data model. Ensure that it is defined as an array type if it is supposed to hold multiple values.
  
  
  Modify the Annotation Usage: If you are using the annotation in your code, ensure that you are passing an array of values instead of a single value. For example, if the annotation is supposed to take multiple entries, ensure you are providing a list or array.
  
  
  Review Data Model: If the annotation is part of a data model (like an OData service), ensure that the underlying data structure supports an array for that annotation.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific annotation you are using. This can provide insights into the expected data types and structures.
  
  
  Testing: After making the necessary changes, test the implementation to ensure that the error is resolved and that the annotation behaves as expected.
