how to send .XLSX File with multiple worksheets as an attachment

Dear All,

I am facing the issue while sending the mail with attachment type .XLSX. for the multiple Worksheets.

we have Tried with below possibilities :

1. Customized SO_DOCUMENT_SEND_API1 and Changed the Document type Size as from ( 3 to 4 ).

2. Tried with CL_BCS Functionality based on the reference Standard program   BCS_EXAMPLE_7

3. Tried with ABAP2XLSX Functionality.

Finally we have achieved to send single worksheet with .XLSX Extension , But its not happening for Multiple worksheets.

Waiting for Solutions.
