MS Excel Option in Custom Report of MM

Hi Sap Gurus,

We build a custom report of MM where in If I click on the Icon of Xl File in the report it is taking me xl file (MS Office Tool) & not displayed the data on the xl file of SAP ALV data,

Anyone have an idea what settings we need to make on MS EXCEL application to display on the sap screen?

Seeking your expert advice.

Regards
