Problem to send Logo in the mail as PDF attachment from Sap-Script

Hi experts,

I've a requirement to send PO to vendor thru mail as PDF attachment. I've developed a z-program using sap-script and send mail from this. I've used FM 'CONVERT_OTF' and 'SO_NEW_DOCUMENT_ATT_SEND_API1' for this and mail hasbeen successfully generated.

But my problem is Company Logo is not printed in the PO when Ive sent it thru mail, but it's shown in print-preview.

Please tell me, how to solve this porblem?

With regards,

Goutam
