How to send mail with zip file

Hi All,

We are sending email in one of our program with an attached xls file. We are sending email using classes (cl_bcs).Our requirement is to send the attached file in zip format to reduce the size.

We have data in table only and while sending mail it gets converted in xls file.

Please provide if you have any pointers to get zipped file in attachment.

Thanks in advance,

Saket
