My Opinion - This type of Updation always Use Database Level triggers.

Update ship_dtl sd
Set sd.rec_qty = nvl(sd.rec_qty,0) + nvl(:ship_dtl.rec_qty,0) 
where sd.mat_code = :ship_dtl.mat_code;

Regards,
Irfan

Sample Code for database Level trigger.

CREATE OR REPLACE TRIGGER DML_SHIP_DTL 
BEFORE INSERT ON SHIP_DTL 
REFERENCING OLD AS Old NEW AS New 
FOR EACH ROW 
BEGIN

 IF INSERTING THEN
 
  UPDATE SHIP_DTL
  SET REC_QTY=NVL(REC_QTY,0)+NVL(:NEW.REC_QTY,0)
  WHERE MAT_CODE=:NEW.MAT_CODE;
  
  
 END IF;
 
END;

Hope it'll help you.

Regards,
Irfan

As my Understanding you have Master - Detail form.
Now you want to total receive qty.
Then You should make report for seeing total qty as following query.

Select Sum(Nvl(Rec_Qty,0)) Received_Qty ,Mat_Code
from Ship_Dtl
Group by Mat_Code;

Irfan

Would you mind to post tables' description? It *must* contain referential integrity constraint so that we'd see how these tables are related. If the data model is correctly set (which includes primary / unique keys), then Forms is capable of creating a master-detail form (using a wizard) which will let you manipulate data correctly. You won't be able to enter duplicate values (because unique index will prevent it). Values that don't exist can be entered freely. The ones that already exist in a table should NOT be inserted but fetched from a database (by executing a query in a form) and then UPDATED.

That's how it is supposed to be done.

If you need to manipulate data manually by considering whether something exists or not, maybe the data model is incorrectly set.
