Have you checked your PO Report to make sure the Document Text is enabled to appear on the report?  It could be the report layout doesn’t include that field out of the box.

Yes.  We can add Document Text manually on purchase order report.

As far as I can tell, that is the same way we have ours setup.  As long as the document text type is the same one used on the report, it should pull through to the report itself.

I assume it is the same document text type in both places, if so, I can’t think of another reason it would appear manually, but not pull through from the supplier.

You at least have confirmed that it is supposed to work as a default.  It is the same Document Text output type on the supplier as one that can be added manually.  Thanks for sticking with me on this but looks like we have something else causing it not to work.

Hi,

This is an old topic, but in case someone finds their way here, here’s the answer: the Document Text which can be set on the Supplier record (or the Customer record in relation to Customer Orders, for that matter) is in fact a different document text than can be manually added on the Purchase Order header. While it appears the document text on the supplier would be defaulted on the purchase order as the document text which can be manually added, it is actually a separate one and its existence cannot be seen on the purchase order record. Even though both document texts work the same way, the one on the supplier record is only fetched when a printout is initiated. This means it is possible to have both the document text on the supplier record and the document text manually added on the purchase order header. While this allows having multiple document texts, it cannot be used to default a document text on the Purchase Order which you could then edit per order, unfortunately.
