Hi,
Pls try -- remove your below code from trigger-
and use in a procedure...I feel you are going wrong in using for "update clause".
Pls go through the docs of how to use "for update" clause with "current of" clause in cursor.
BEGIN
FOR i IN C1 LOOP
SAVEPOINT a;
SELECT Booked_Flag
INTO Flag_Update
FROM Oe_Order_Lines_All
WHERE Header_Id = i.Header_Id
AND Org_Id = 121
FOR UPDATE Wait 10;
IF Flag_Update = 'Y' THEN
UPDATE Oe_Order_Lines_All
SET Project_Id = v_Pa_Proj_Seq_Nxtval
WHERE Header_Id = i.Header_Id
AND Org_Id = 121;
COMMIT;
ELSE
UPDATE Oe_Order_Lines_All
SET Booked_Flag = 'Y'
WHERE Header_Id = i.Header_Id
AND Org_Id = 121;
ROLLBACK TO a;
END IF;
END LOOP;
END;
