report 10.6 info

Hi all,

I've to personalize the standard report of Purchase orders. I've also to add at the end the "buyer sign" based on the subject of the order, how can i do this?

The buyer sign should be a Text field, that contains the signs of the buyers ?
If it's a field of another table, i've to select it from a report extension, then insert it into the report designer?

Thanks in advance
