PO history category L

Hello all,

I'm using bapi BAPI_PO_UPDATE_HISTORY to update a PO history with a FI document.

The history category is hardcoded in the bapi and is L - Delivery Note.

In the PO history tab I can't visualize the document when I click in the document number. Is this a standard behaviour of the po history category 'L'?

Thank you,

RS
