Dear All,

I need to get the running total of differences between Received quantity and ordered quantity

lets say : if I ordered from ITEM 'X' a quantity of 300 Pcs, and I received the following quantity as the following schedule :

1- GRN 1 QTY = 20, I need the running total to be showing 280
2- GRN 2 QTY = 80, I need the running total to be showing 200
3- GRN 3 QTY = 120, I need the running total to be showing 80

thus please look into the following code :



create table local_purchase_order
(
po_txn_code  			  varchar2(3),
po_no        			  number(6,2),
po_date      			  date,
po_item_code 			  varchar2(8),
po_unique_reference_code          varchar2(6),
po_quantity  			  number(8,2));

ALTER TABLE local_purchase_order ADD CONSTRAINT UNQ_PO_REF_PK PRIMARY KEY (po_unique_reference_code);

create table good_receipt_note 
(
grn_txn_code   				varchar2(3),
grn_no         			        number(6,2),
grn_date       			   	date,
grn_item_code  			   	varchar2(8),
grn_unique_reference_code               varchar2(6),
grn_quantity   				number(8,2),
PO_UNQ_REF_CODE				varchar2(6))

ALTER TABLE good_receipt_note ADD CONSTRAINT UNQ_GRN_REF_PK PRIMARY KEY (grn_unique_reference_code);


ALTER TABLE good_receipt_note
add CONSTRAINT GRN_PO_FK
  FOREIGN KEY (PO_UNQ_REF_CODE)
  REFERENCES LOCAL_PURCHASE_ORDER(PO_UNIQUE_REFERENCE_CODE);
  

insert into local_purchase_order values ('LPO',1001,'01-JAN-2010','C1000101','REF201',550);

insert into local_purchase_order values ('LPO',1010,'10-JAN-2010','C1000120','REF202',200);

insert into good_receipt_note values ('GRN',1101,'03-JAN-2010','C1000101','GRN800',100,'REF201');

insert into good_receipt_note values ('GRN',1102,'05-JAN-2010','C1000101','GRN801',50,'REF201');

insert into good_receipt_note values ('GRN',1103,'09-JAN-2010','C1000101','GRN802',80,'REF201');

insert into good_receipt_note values ('GRN',1104,'22-JAN-2010','C1000101','GRN803',70,'REF201');

insert into good_receipt_note values ('GRN',1105,'03-FEB-2010','C1000101','GRN810',50,'REF201');

insert into good_receipt_note values ('GRN',1106,'15-JAN-2010','C1000120','GRN811',20,'REF202');

insert into good_receipt_note values ('GRN',1107,'31-JAN-2010','C1000120','GRN812',80,'REF202');

insert into good_receipt_note values ('GRN',1108,'18-MAR-2010','C1000120','GRN813',40,'REF202');


commit;

LPO	1010	1/10/2010	C1000120	REF202	GRN	1108	3/18/2010	200	40



then if it's possible to have last result (last row) for each item in each po

thus it would be like this :
Total PO Qty        Total GRN Qty    Balance 
300                 220              80


and now the most complix condition which it's difficult to acheive: that if I need to show only those requested ITEMS in PO's whose having a pending quantities to be delivered.

can any one help me, please

Remember:
1/ A statement ends with "/" or ";", your second create table misses them
2/ '01-JAN-2010' is not a DATE but a STRING:
SQL> select to_date('01-JAN-2010') from dual;
select to_date('01-JAN-2010') from dual
               *
ERROR at line 1:
ORA-01858: a non-numeric character was found where a numeric was expected

3/ Column in results should be align to be readable. Do you provide such report to your boss?
It's easy:

How do you calculate your "crt. bal"?
What prevent you from modifying my query to fit your needs?

Is not working is not an Oracle error.
Same remarks.

Please explain.

I think you should have a closer look at your own data.
I modified the first query then you will understand:

If it is wrong, EXPLAIN why.

Change your SQL*PLus to something that is greater, at least 9.2.
The problem is not your database, just your SQL*Plus.
