Thanks for POP

Makes sense what you said using ACC code as that wont change.
Managed to get it to work with the below expression

Remaining > 0 AND (PURCHASE_ORDER.ACCOUNT_REF = "POLSPAIN" OR PURCHASE_ORDER.ACCOUNT_REF = "POLYNTFR" OR PURCHASE_ORDER.ACCOUNT_REF = "POLYNTIT" OR PURCHASE_ORDER.ACCOUNT_REF = PURCHASE_ORDER.ACCOUNT_REF = "POLYNT")
However, is there a way I can get it to only show POLYNT acc ref outstanding purchase orders for purchase orders that only contain certain prods?
Certain POLYNT prods SKU numbers: 1100
1103
1104
1105
1110
1120
3070
3100
1104
1111
Ive tried the below and it doesnt work:
Remaining > 0 AND ((PURCHASE_ORDER.ACCOUNT_REF = "POLSPAIN" OR PURCHASE_ORDER.ACCOUNT_REF = "POLYNTFR" OR PURCHASE_ORDER.ACCOUNT_REF = "POLYNTIT" OR PURCHASE_ORDER.ACCOUNT_REF) OR (PURCHASE_ORDER.ACCOUNT_REF = "POLYNT" AND POP_ITEM.STOCK_CODE = “1100” OR “1103” OR “1104” OR “1105” OR “1110” OR “1120” OR “3070” OR “3100” OR “1104” OR “1111”))
Reading the sage help forum now but struggling a bit trying to reverse engineer expressions from other reports to get the method.
Any help much appreciated
