Append or Merge Direct Query BW & Excel

Hi All,

I want to learn is it possible to use composite model method for SAP BW Direct query + Excel.

https://docs.microsoft.com/en-us/power-bi/desktop-composite-models

Actually it is not important to use composite model method. Our datasource is SAP BW, we will use direct query mode and we want to import data from excel to BW Query in Power BI. I want to make sure there is any method to do this.

Regards
