Attaching a URL which does not start with HTTP / HTTPS in SAP TM

Dear Experts,

I am trying to insert a new URL to a Attachments table in FWO / FRB application.

My URL neither start with HTTP  nor HTTPS (Ex: Z3://searchsmartstart...). while I am trying to insert such URL, I am getting an error message 'URL not valid.Check if the URL contains the protocol (HTTP/HTTPS). Message ID - /SCMTMS/UI_MESSAGES and message number 088.

After some analysis, I have understood that WebDynpro ABAP framework does not accept such URL.

Could you please guide, is there any other way of doing it? The URL which I am trying to access is of SMART CLIENT.

Thanks in advance for your reply.

Thanks,

Bharath.K
