SAP_CONVERT_TO_XLS_FORMAT and TEXT_CONVERT_XLS_TO_SAP is not Supporting for FIORI App

Hi Friends,

I created one report for Purchase info records updating purposes. wheres as I used SAP_CONVERT_TO_XLS_FORMAT and TEXT_CONVERT_XLS_TO_SAP for upload and download excel documents. everything is working fine yet.

Now, this report would like to use in the Fiori launch pad. but these two function modules are not supported. can you please suggest to me any other support classes or FM for upload and downloading excel files.

Regards,

Ravi
