1. Could you please provide the error message you are receiving?
2. what is the datasource type you are trying to refresh? Is it an extract?
What is the type of data source you are using?
There is the option to replace a data source in the data menu, so you could potentially add a new source each time and replace the references if the data source is the same structure.
Error is " An Error Occurred while communicating to Data Source "
I am using excel file (.Xlsx) .Yes it is extract.
Excel file (.xlsx) as source file . Yes replace works fine but i need to use edit data source but it does not work .
If the spreadsheet is in the same format you should just be able to replace the file and refresh your data source.
You might have some problems if excel is editing it at the same time as tableau is trying to access.
