We need more details about your app.
Are you sure your extraction is running without errors?
Your csv files need the same name, same column names and same location in server and local desktop. Are you using extractions?
its running without errors. but the .csv file name i'm using is different. old one is omni_0000 and new one is omni_0000_updated. same column names and same location in server and local desktop
It has to be the same name.
You are probably running without erros because you have the old file in server.
You are updating extracts with the same data.
Ok. If I use same names will it get updated in server also? or Do I need to do anything for this?
If your extraction is correct it will work with the same name.
Ok. Thank you so much. Can you explain me about extraction?
An extract is a .tde file which you load from files or databases.
This kind of files optimize reading from Tableau.
When you build an extract, it keeps information from where it was loaded. That's why files needs to have the same name.
I'm not good to explain this. See this link:
