This error indicates that a required annotation for draft persistence is missing in the specified CDS view.
  Cause:
  The error is caused by the absence of the necessary annotations in the CDS view that define how draft data should be handled. Draft persistence is essential for applications that require the ability to save incomplete data entries temporarily. If the annotations are not defined correctly, the system cannot manage draft data, leading to this error.

  @ObjectModel.draft.enabled: true - This annotation enables draft handling for the view.

  @AbapCatalog.sqlViewName: 'Z_MY_CDS_VIEW'
  @AccessControl.authorizationCheck: #CHECK
  @ObjectModel.draft.enabled: true
  @ObjectModel.draft.persistent: true
  define view Z_MY_CDS_VIEW as select from my_table
  {
      key field1,
      field2,
      ...
  }
