During scanning in Assembly you might come across the error " barcode in not valid"
It means that you scanned a barcode that does not exist either in an open order or in the system at all. There are two main causes for this,
The first is that the item has more than one barcode and the barcode you scanned was never entered into the current open order. Look for another barcode, if you find it, scan it and your item should assemble.
The second common cause, especially when beginning to barcode, is that the item had a barcode heat sealed onto it but the barcode was never scanned/entered into the system. This is why it is very important to follow the numerical sequence of the barcodes when detailing.
