Tax does not appeard

Hello ,

I’m encountering an issue when creating a new invoice linked to a Purchase Order (PO): the classification code field is coming up empty. The root cause seems to be that the user did not enter the tax information in the PO. However, this problem occurs for all suppliers when I create an invoice based on a PO.

Normally, the tax should be automatically generated based on the supplier’s setup. So my question is: what should I check in configuration to ensure the tax is correctly applied when creating the invoice?

Thank you,
