I'm not quite sure what you mean with
But the document number is not pass to the called form field and : H_DOC_CODE is a field in the called form.Do you want that the form is in ENTER-QUERY-mode and the field H_DOC_CODE contains the field of the GLOBAL?
Or do you want to automatically execute a query with that H_DOC_CODE.
For the first, you have to assign the global in the WHEN-NEW-RECORD-INSTANCE-trigger instead of the PRE-QUERY:
IF :SYSTEM.MODE='ENTER-QUERY' THEN
  :H_DOC_CODE :=:global.offer_no ;
END IF;For doing an automatic query the suggested solution with the PRE-QUERY-trigger is right, but you would have to issue an EXECUTE_QUERY in the WHEN-NEW-FORM-INSTANCE instead of an ENTER-QUERY.
