sap adobeform sending pdf as attachment with specific name

Hi Experts,

Need your help in solving my problem !!

My requirement is to send adobe form as mail attachment in PDF format, Which I am able to do.

My Problem is PDF attachment should be generated with specific name.

For example my scenario (below given screen shot),

When i click on submit by email button, PDF will be attached to my mail,

with some random name such as "d4811f8_45171.pdf" Instead it should be generated with

fixed name such as "new_attach.pdf" or dynamic name using user name such as

"Vishwa_attachment.pdf".

Kindly help to achieve my needs.

Any help will be greatly appreciated and rewarded.

Thanks in advance,

Regards,

Vishwa
