SO_DOCUMENT_SEND_API1 receiver placed in CC

Hi Friends,

I am using FM SO_DOCUMENT_SEND_API1 to send email to external address. Everything is working fine except that the email address is placed in the CC: section instead of TO:

I have the following code and pass internal table gt_mailrecv in the function module.

gs_mailrecv-receiver = emailid.

gs_mailrecv-rec_type = 'U'.

gs_mailrecv-rec_date = sy-datum.

gs_mailrecv-express = 'X'.

APPEND gs_mailrecv TO gt_mailrecv.

Any idea why?

Thanks,

Nene
