  The SAP error message SDDIC_ADT_DDLX010 typically occurs in the context of the ABAP Development Tools (ADT) when working with annotations in your ABAP code. This error indicates that there is a mismatch between the expected type of an annotation value and the actual type provided.
  Cause:
  The error message Annotation value of '&1' must be of type '&2' suggests that:
  
  You are trying to assign a value to an annotation that does not match the expected data type.
  For example, if an annotation expects a string but you provide a number, or if it expects a specific enumeration type and you provide a different type.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check the Annotation Definition: Look up the documentation for the specific annotation you are using. This will help you understand what type of value is expected.

  If it expects a specific enumeration, ensure you are using one of the defined values.
  
  
  
  Correct the Code: Modify your ABAP code to ensure that the value assigned to the annotation is of the correct type. For example:
  @AbapCatalog.sqlViewName: 'ZMY_VIEW'
  @AbapCatalog.compiler.compareFilter: 'MY_FILTER'
  @EndUserText.label: 'My View'
  define view ZMyView as select from my_table
  {
      key field1,
      field2
