I'm hoping someone can help me. I am having trouble appending data to a csv published data source. What my organization is trying to accomplish is appending data daily to my published workbook. But every time I try to append the data, it overrides the previous days data. Is there something I am missing here?
It sounds like you are trying to set up an incremental extract refresh with Excel. Check out this Quick Start Guide and see if that gets you to where you need to go: Quick Start: Incremental Extract Updates
Hope that helps!
