can't you set IPO_No,Item_No,Line_Item_Seq_No and Release_No as composite primary key? then you will get exception when you try to insert same value. in case of exception you can increase the Release_No and try again until success.

actaully po_no,Item_no,line_item_seq_no are from po_master and po_item table respectively

Hello,

Please try below query and let me know if it helps your need.

SQL

with ctetest  (IPO_No,Item_No   ,Line_Item_Seq_No  ,Release_No) as
(
select 15063    AS IPO_No, 11104    as Item_No  ,1 as   Line_Item_Seq_No  ,1 as Release_No
union all
select 15063    AS IPO_No, 11104    as Item_No  ,1 as   Line_Item_Seq_No  ,1 as Release_No
union all
select 15063    AS IPO_No, 11104    as Item_No  ,1 as   Line_Item_Seq_No  ,1 as Release_No
)

select IPO_No,Item_No,Line_Item_Seq_No,ROW_NUMBER() over (order by IPO_No asc) Release_No from ctetest

Thanks,
