In the Canvas application, if I scan for data that doesn't exist, it's true that there's no data in the application, but if I scan for data that's already in the database and it's retrieved, and then I scan for data that's not in the database, then I find that instead of displaying a blank space, it's displaying the last retrieved result, and then it's displaying the last retrieved result.

Hi @Elmer_Wan ,

Please try this in the OnScan of BarCode Reader:
If(IsBlank(BarcodeReader1.Barcodes),ClearCollect(Col,Blank()),ClearCollect(Col,Filter('0807-3',Title = First(BarcodeReader1.Barcodes).Value)))
Hope this will help you,
Best Regards,
Tina
