Item Cross-Reference for Microsoft Dynamics 365 Business Central
Every warehouse has vendors who change barcodes without notice, new items arriving without pre-mapped codes, and supplier labels that have never been seen before. The traditional response is to flag the item, set it aside, and have someone in the office map the barcode to the correct Business Central item before receiving can continue.
Warehouse Insight eliminates that loop entirely. When a worker scans an unknown barcode at the receiving dock, the device immediately prompts them to link it to the correct item on the purchase order. The cross-reference is created in Business Central on the spot, and the next time that barcode is scanned anywhere in the system, it resolves correctly.
At a Glance
- Unknown vendor barcodes trigger an immediate on-device prompt to link the barcode to a Business Central item, right at the receiving dock.
- The cross-reference is live in Business Central the moment the worker confirms it, with no admin follow-up or office involvement required.
- Multiple barcodes per item are supported, handling vendors who assign different codes to the same product across shipments.
- Cross-reference creation can be enabled or disabled per device configuration, allowing supervisors to control who can create new mappings.

Key Capabilities
On-the-fly cross-reference creation at receiving. When a worker scans a barcode that Business Central does not recognize, Warehouse Insight displays a dialog listing the purchase order lines that have not yet received a quantity. The worker selects the correct item from the list and confirms. The barcode is immediately added to the item’s cross-references in Business Central. From that point forward, scanning that barcode anywhere in Warehouse Insight automatically resolves to the correct item.
No interruption to the receiving workflow. The unknown barcode prompt appears inline within the receiving application. The worker identifies the item, confirms the cross-reference, and continues receiving without exiting the application, returning to a desktop, or waiting for someone else to make the mapping. The receiving document stays open throughout.
Multiple barcodes per item. Business Central’s item cross-reference supports multiple barcode entries per item. Warehouse Insight creates each new entry independently, so a vendor who assigns different barcodes to the same item across different shipments does not create a recurring problem. Each new code is mapped once and resolves correctly on every subsequent scan.
Handles changes to vendor barcodes without disrupting the workflow. When a supplier changes their barcode, the first scan of the new code prompts the cross-reference dialog. The worker maps the new code to the existing item. Receiving continues. The old code remains valid in Business Central alongside the new one, so any remaining stock labeled with the old barcode continues to scan correctly elsewhere in the warehouse.
Configurable per device. Cross-reference creation is controlled by the Unknown Scan Behavior setting in Business Central’s device configuration. Setting it to Ask User enables the on-the-fly prompt. For operations that want to restrict which workers can create new cross-references, the setting can be left disabled on general receiving devices and enabled only on supervisor-level configurations.
Supports international and non-standard barcode formats. Warehouse Insight accepts barcodes in any format the device scanner can read, including UPC, EAN, GS1, Code 39, Data Matrix, and others. Unknown barcodes in any of these formats trigger the same cross-reference prompt, regardless of the barcode symbology used by the vendor.
How Item Cross-Reference Works in Warehouse Insight
Item cross-references in Business Central link external barcodes, such as vendor-assigned codes, UPC labels, and customer item numbers, to internal BC item numbers. When a worker scans a barcode during any Warehouse Insight workflow, the system looks up that barcode in BC’s cross-reference table and resolves it to the correct item. Pre-mapping known vendor barcodes in Business Central before goods arrive is the preferred approach and eliminates the need for a lookup step entirely.
For barcodes that are not yet mapped, Warehouse Insight’s Unknown Scan Behavior setting determines what happens at the moment of scan. When set to Ask User, scanning an unrecognized barcode during receiving opens a dialog showing all purchase order lines that have not yet had a quantity received against them. The worker identifies which item the scanned barcode belongs to, selects the line, and presses OK. Warehouse Insight writes the barcode to the item’s cross-reference record in Business Central immediately. The dialog closes, and the receiving workflow continues with that item’s line now selected and ready for quantity entry.
The cross-reference created on the device is identical to one created manually in Business Central. It appears in the item’s cross-reference list, is available for use across all Warehouse Insight applications, and persists across sessions and devices. No synchronization step is required.
Why On-the-Fly Cross-Reference Building Matters
The daily friction point this feature removes is specific and familiar to anyone who manages inbound receiving—a vendor ships without pre-notice of a barcode change. A new product arrives with codes that were never entered into the system. A seasonal supplier reuses item numbers with new barcodes. In each case, the traditional response requires a worker to stop, flag the item, and wait for someone with Business Central access to map the code before receiving can proceed.
Warehouse Insight moves that resolution to the dock and to the worker holding the item at the moment the problem occurs. The worker does not need Business Central access beyond the receiving application. They do not need to know the item number. They see a list of items on the purchase order that still need to be received and select the one that matches what they are holding. The mapping is made, and receiving continues in under a minute.
For high-volume receiving operations where vendor barcode consistency is unreliable, this removes a category of receiving delays that would otherwise accumulate across all affected shipments.
Who Uses Item Cross-Reference
Receiving clerks use the on-the-fly cross-reference prompt during daily receiving operations whenever an unknown vendor barcode is scanned. The prompt appears automatically when the Unknown Scan Behavior is set to Ask User, so workers do not need to take any special action to trigger it. Warehouse supervisors and Business Central administrators manage the device configuration setting that controls whether cross-reference creation is available to general receiving staff or restricted to specific device configurations. Purchasing managers benefit indirectly: vendor barcode changes that previously caused receiving delays are now resolved at the dock without the purchasing team’s involvement.
Frequently Asked Questions
When a worker scans a barcode that Business Central does not recognize during receiving, and the Unknown Scan Behavior device setting is set to Ask User, Warehouse Insight displays a dialog showing all purchase order lines that have not yet had a quantity received. The worker selects the correct item from the list and confirms. Warehouse Insight immediately adds the scanned barcode to that item’s cross-reference record in Business Central. From that point forward, scanning the same barcode anywhere in Warehouse Insight automatically resolves to the correct item.
Yes. The cross-reference is written to Business Central when the worker confirms the mapping on the device. No synchronization step or manual follow-up is required. The new entry appears in the item’s cross-reference list in Business Central immediately and is available across all Warehouse Insight applications and devices from that point forward.
Yes. Business Central’s item cross-reference supports multiple barcode entries per item, and Warehouse Insight creates each entry independently. A vendor who uses different barcodes for the same item across different shipments, or who ships the same item under different internal codes for different customers, can have each code mapped to the same Business Central item. All mapped barcodes resolve correctly on every subsequent scan.
Yes. Cross-reference creation is controlled by the Unknown Scan Behavior setting in Business Central’s device configuration. Setting it to Ask User enables the on-the-fly prompt for that device configuration. Leaving it at the default setting means unknown barcodes are flagged as errors rather than triggering the cross-reference dialog. Operations that want to restrict cross-reference creation to supervisors or experienced receivers configure the Ask User setting on those device configurations only, leaving general receiving devices with creation disabled.
The on-the-fly cross-reference creation prompt is specifically designed for the receiving workflow, where unknown vendor barcodes are most commonly encountered and where the purchase order lines provide the context needed to identify the correct item. In other workflows, an unknown barcode displays an error, and the worker can enter the item manually using the Enter Item fallback option. Cross-references created during receiving are immediately available in all other workflows, so the mapping built at the dock resolves correctly across picking, shipping, counting, and all other Warehouse Insight applications.
