Information Broadcasting - View as MS Excel

Hello,

I want to broadcast a query view in MS Excel format . I want to add my company logo in the output of the view.

Therefore , I have created a broadcasting settting on the view , selectetd MS Excel as Output format.

I also enhanced 0QUERY_TEMPLATE_BROADCASTING70 to ZQUERY_TEMPLATE_BROADCASTING70 and added my company logo

by inserting the picture in the template. Also , assigned the ZQUERY_TEMPLATE_BROADCASTING70 template in SPRO -> Broadcasting -> Query Pre Calculation. .

Output of the broacasted email , does not reflect the enhancement. This is not working for me. Please advice if I am missing something or my approach is incorrect.

Is there a default template which SAP uses to precalculate Views in excel ?
