When you scan a barcode in a warehouse mobile flow in Business Central, the system treats the scan exactly like a series of keystrokes. If you scan item number 5000, the scanner reads the barcode and enters 5000 just as if you had typed it on the keyboard. From there you can see the bin content for that item.
The useful part is what happens behind the scenes. Business Central does not only match the exact item number. It runs through a defined search logic that lets you scan several different barcodes and still land on the same item. You set this up through the item card and the item references, and the logic applies across all the mobile flows where you look up items.
Scanning a barcode works like keyboard input
A barcode scanner behaves like a font on the keyboard. When you scan a normal barcode, the scanner understands the value and types it in for you. So scanning the barcode for item 5000 gives the same result as keying in 5000 manually. You can scan numbers directly, and the flow reacts the same way whether you typed or scanned.
In practice this means you can have several barcodes that all point to the same item. For example, barcode number 37 opens item 5000, and so do barcodes 36 and 34. They all resolve to the same item because of the search logic running underneath.
How Business Central searches for the item
When you scan for an item, Business Central follows a fixed order to find a match:
- Item number first. The system checks the item card to see if the scanned value matches an item number.
- GTIN (Global Trade Item Number) next. If there is no item number match, it searches the GTIN field to see if that gives a hit.
- Item references last. If neither of those match, it searches the item references, where you can add as many barcodes as you want for a single item.
This is why scanning barcode 34 or 36 still opens item 5000. Those values are stored as item references on the item, so the search logic finds them at the third step.
The same logic applies across all mobile item lookups
You do not have to configure this separately for each function. The standard warehouse mobile uses this search logic everywhere you look up an item. That includes find items, show bin content, warehouse receive, and the other flows where you scan for an item number. Set up your item references once, and every flow that needs to identify an item will use the same matching behaviour.
Q&A
What happens when you scan a barcode in Business Central warehouse mobile?
The scan works like keyboard input. The scanner reads the barcode and enters the value just as if you typed it, then the flow looks up the matching item.
In what order does Business Central search for a scanned item?
It searches the item number first, then the GTIN (Global Trade Item Number), and finally the item references. The first match wins.
Can one item have more than one barcode?
Yes. You add as many barcodes as you want through item references, and they all resolve to the same item.
Do you need to set up barcode scanning separately for each mobile flow?
No. The standard warehouse mobile uses the same search logic everywhere you look up an item, including find items, show bin content, and warehouse receive.
