Customizing PO number to add a prefix 'AB' on the number generated.

Question

Hi All
I have a requirement to customize the PO number on the Purchase Order form, when a user create a new PO manually.
Below is the code, could someone please point to the right direction on this issue.
form_name VARCHAR2(30) := NAME_IN ('system.current_form');
block_name VARCHAR2(30) := NAME_IN ('system.cursor_block');
item_name VARCHAR2(30) := NAME_IN('system.cursor_item');
l_order_num VARCHAR2(25):= 'MP13/1000'; --:= select 'MP'||to_char(sysdate, 'YY')||'/'||AP.XXAP_VENDOR_NUM_S.NEXTVAL from dual;
Begin
IF event_name = 'WHEN-NEW-FORM-INSTANCE' THEN
IF form_name = 'POXPOEPO' THEN
IF block_name = 'PO_HEADERS' AND item_name = 'VENDOR_ORDER_NUM' THEN
l_order_num := 'MP'||to_char(sysdate, 'YY');
-- if NAME_IN('PO_HEADERS.VENDOR_ORDER_NUM') = 'Y'THEN
IF l_order_num IS NOT NULL THEN
copy (l_order_num,'PO_HEADERS.VENDOR_ORDER_NUM'); --output sample MP13/1000
fnd_message.set_name('FND','Purchase Order Number '||l_order_num||' created - TEST');
ELSE
fnd_message.set_name('FND','Creation of Purchase Order Number NOT created - TEST');
fnd_message.Error;
RAISE FORM_TRIGGER_FAILURE;
END IF;
-- disable the field after being populated
SET_ITEM_PROPERTY('PO_HEADERS.VENDOR_ORDER_NUM',UPDATEABLE,PROPERTY_FALSE);
End if;
-- End if;
End if;
End If;
Running
RDBMS 11.1.7.0
Oracle applications 12.1.3
form Name POXPOEPO
Thanking you in advance
