Create a new operation named Delete that uses the book entry point.
Reusable fields you created in a different operation remain visible for all operations.
Create a COBOL Assignment for the lnk-function field and set its value to 3. This is the value that instructs the program to delete a record.
Create an interface field named lnk_file_status from the COBOL Entry Point field link-file-status; then set the direction to Output. This is the only required output field.
Drag lnk_b_details from the Reusable Fields pane to the Interface Fields pane and rename the new interface field delete_input.
Save the service interface.
This completes the Delete operation and the ProgramEJB service interface definition..
