Show Pop-Up if barcode value already present while scanning

[PurpleDeveloper]

Hi Team,

I have added a barcode scanner to scan the items. I would like to know how to put a condition on 'OnScan' property to check if that barcode is already present in the CDS table and status is in 'New' and also to show a pop up on the screen while scanning that barcode is already scanned or so..

Any help is really appreciated.

I actually meant my post - but that is up to you.
