Business Central 27.3 Bug: Item Lookup Not Working After Upgrade (Known Issue & Workarounds)
Business Central 27.3 Bug is causing widespread issues for users after upgrading, particularly affecting the Item Lookup functionality in Sales Orders. Many customers have reported that after upgrading to version 27.3, searching for items in the full Item List freezes the web client. Users cannot select an item or click OK or Cancel without refreshing the browser, often losing unsaved work in the process.
This Business Central 27.3 Bug is not caused by customizations, extensions, or data corruption—it appears to be a platform-level regression introduced in the web client. Businesses that rely heavily on Sales Orders and item lookups are experiencing significant operational disruptions, making it a critical issue to address before upgrading.
What Happens With the Item Lookup?
Here is a typical scenario that triggers the issue:
- Open a Sales Order.
- Go to the Lines section.
- Open the Full Item List to search for an item.
- Enter the Item Name.
- Select the item or click OK / Cancel.
At this point, the page becomes unresponsive. Buttons stop working, record selection does not register, and users must refresh the browser session. For companies processing high volumes of orders, this is a major productivity issue.
Other Regressions in Business Central 27.3
In addition to the Item Lookup freeze, users have reported other issues that suggest platform-level regressions in version 27.3.
Tooltip Media Not Rendering
Previously, hovering over fields like Source No. in Planned Production Orders displayed a tooltip with metadata and an item image (Media / MediaSet). After upgrading to 27.3, the tooltip still appears, but the image preview no longer renders. This removes a helpful visual reference for end users and indicates a regression in how media is handled in tooltips.
Report Request Page Buttons Not Responding
Some customers reported that Report Request Pages stop responding after filters are applied. Users can open the page and set filters, but buttons like Run or Cancel do not always work. The issue appears inconsistent across browsers, making it unpredictable and harder to manage.
Performance Issues on the Items Page
Some tenants have observed a slowdown when loading the Items list page. Pages that were previously fast now take significantly longer to render, affecting daily operations.
Is This a Known Issue?
Yes. Community moderators and experienced partners have confirmed that this is a known regression in Business Central 27.3. Microsoft is reportedly working on a fix, but as of now, it is not clearly documented in the official release notes or known issues list.
Because this Business Central 27.3 Bug is not yet fully addressed by Microsoft, customers should carefully evaluate upgrading production environments until a fix is released.
Temporary Workarounds
Until an official fix or cumulative update is released, there are a few ways to reduce disruption:
- Enter the Item No. directly instead of using the full Item Lookup search.
- Open the Items list in a separate tab, search manually, then copy and paste the Item No. into the Sales Order line.
- Test version 27.3 in a sandbox environment before rolling it out to production.
- Delay upgrading if your business relies heavily on Sales Orders and item lookup functionality.
While these solutions are not perfect, they can help maintain workflow continuity until Microsoft releases a permanent fix.
Should You Upgrade to Business Central 27.3?
If your business relies heavily on:
- High-volume Sales Orders
- Production planning workflows
- Item Lookup functionality
- Custom reports
then upgrading immediately to version 27.3 may introduce unnecessary risk.
Minor updates are generally safe, but this one includes a critical bug affecting the web client. The safest approach for production environments is to pause upgrades and monitor Microsoft’s updates for a fix.
Key Takeaways
- Business Central 27.3 Bug causes Item Lookup in Sales Orders to freeze.

- Other regressions include missing tooltip images, report page button failures, and performance issues on the Items page.

Companies should test carefully, consider temporary workarounds, and delay production upgrades until Microsoft releases a confirmed fix.
Staying informed and cautious can save your team from major disruptions.
