Add inventory using scanner/barcode

[ksjoberg]

Adding new inventory, such as the item in an delivered order is cumbersome, as the part need to be searched and/or added, edited, click "add stock" and then filling in the location and item count, followed by a click on Save.

The EIGP114 barcodes contain many of these datapoints. By scanning the bag, the part can be identified or added using the InfoProviderSystem. The added stock quantity is also in the EIGP114 data, so by picking the storage location the item could be quickly added.

I would love this feature! I have a lot of LCSC parts, and if I could just scan the qr code to create the part, it would be awesome.
