Proportional Non proportional font in SAP inbox

Hello,

I am sending a documnet using the FM SO_OBJECT_SEND.

When I see the document content in SAP inbox(tcode SBWP), my document is shown in proportional font by default, however my requirement is to show the contents in non-proportional font. (Transaction code SBWP, clik on the Inbox node, open any document, on the menu double click at 'Settings'). Could anybody provide my requiremnt that whenever I open the document generated through the FM should always be opened in Non-proportional font.

A meaningful, early will be great help for me and worth for my rewards points.

Thanks,

Amarjit Singh
