Excel connection always looking for File template while running through Job

Hi All,

I am reading data from excel file.

Now during development I have used A.XLSX file used related connectionstring.

Now when I move to production, I don't have A.xlsx file exist as I am passing Name through variable.But Package always intitally tried to bind A.XLSX.

So Do I need to Keep always A.xlsx file in the folder as a template ?
