This warning typically appears when:

You're trying to post or process a purchase order line that is intended to be linked to a Job, but the Line Type field (which should indicate whether it's a Budget, Schedule, or Contract line) is left blank.

Business Central uses the Line Type to determine how the cost or usage should be tracked against the Job Planning Line.

Recommended Actions
Here’s how you can address this:

Check if the PO is linked to a Job:

Go to the Job No. field on the purchase line or header.

If it's filled, this PO is expected to post usage to a Job.

Set the Line Type:

Navigate to the Job Planning Lines.

Ensure that the Line Type (e.g., Budget, Schedule, Contract) is correctly set for the line you're referencing.

If you're not referencing a specific planning line, you may need to create one or clarify the intent of the PO.

Decide based on business logic:

If this PO is not meant to be tracked against a Job, you can safely click Yes to continue.

If it should be tracked, click No, and update the Line Type accordingly.

Hi,

It looks like that your Purchase order is linked to any Project and Task.

Also the planning line to which it is linked does not have the Line type selected. The Line type has three options Budget, Billable and Budget/Billable. You need to select appropriate option in your planning line or lines in order to process and then this pop-up message will not appear.

I hope this helps.

Regards,

Dhiren

You have "Apply Usage Link" enabled on your Project, which is what you want. However, you likely created the PO manually, so it doesn't have all of the fields filled that the Planning Worksheet suggestion would fill, OR the Item is not present on the Project Budget. Both are perfectly okay, and won't hurt your Project in any way.

The message simply means it will not be updating any existing Project Planning Lines when you record the receipt of the material. The Project will still have the Project Ledger updated (when the PO's Invoice is posted).

This is simply a warning message due to the "Apply Usage Link" field. Again, it is better in 99% of cases to have this field enabled.

Best Regards,

that message means your project planning line is missing a Line Type (e.g. Budget or Billable). Without that, Business Central can’t link actual usage back to the planning line.

Fix: Open the planning line, set the correct Line Type, then post usage again — it should link properly.
