Hi Sandra,
Thank you, lv_name no contains the zip file name, I already insert the name and the zip file is recognized in gmail, but the txt file not have format columns, I already use cl_abap_char_utilities=>CRLF but it did not work,
I already sent only a txt file using cl_abap_char_utilities not zip => CRLF, the SCMS_TEXT_TO_BINARY function and then the method add_attachment and it worked correctly but the file is very big and I need zip.
Best regards,
Robert
