To continue from following post as it’s closed, we face issue as narrated below.
Now, here we face another issue. When we put value in print heading (For Eg. “Proforma Invoice”) it shows the heading. But when there is no value in Print Heading Field, it shows none.
For Standard Print format, it shows the value as doc name (i.e. in this case “Sales Order”) if Print Heading field is blank.
