Item_Transfer

Add "sublot_no" before "grade_cd" and "from_ sublot_no" before "from_grade_cd" (both string40, nullable) to store the current and previous sublot numbers of the item that was transferred.

Add "from_wo_id", "from_oper_id" (both string40, nullable), and from seq_no (int32, nullable) before "from_ent_id" to record changing which job produced the material represented by a certain inventory record.

Add set-null foreign keys from "grade_cd" and "from_grade_cd" to item_grade, and from "status_cd" and "from_status_cd" to item_state.
