Hi ..


i got issue from my customer that user when scan barcode of item XXXXXXX it gives in receipt different reading for barcode YYYYYYY which is belong to different item, so different description and price printed on the receipt.

the user scan again after few time, correct description is coming , i reviewed the item and barcode update everything is fine and no change happend in this period.

any explanation is't application problem or related to hardware ( scanner celebration).


thanks for you usual support.

    did you debug and check the barcode value during runtime?
    try to remove the object metadata records of the used objects and restart the nav service.
    write a simple codeunit to test if the scanning and reading of item data works correct.

    Hi

    Actually it's not happen contentious, maybe one time within the month.

    it's happen during the transaction and no body can track it, other wise i have to keep debug running for all POS which is not recommended.

    The Question here what is the possibility to happen this :
    1- While scanning the barcode?
    2- There is bug in the codeunit?
    3- The problem came from the scanner (flat scanner)?
    4- or the item itself have bad barcode printing.

    hi,

    one time per month is quite strange.
    so best to avoid wrong labels/reports add some error handling, validations on appropriate positions.
    display a preview or an info page with detailed infos before concrete printing to check what is going to the output.

    for analysing act like an engineer:
    exclude error reasons step by step.
    * start with a clean new test database
    * try different scanners
    * write a new, quite simple test codeunit for testing the scanning process
    * add a detailed logging mechanism for your process (scanning, processing the read barcode, reading item data, printing, ...)
