Currently i have huge data which is almost 3GB of data(.csv). I have to do few modifications to that data so i'm using Altreyx and outputting it in .tde format as file size is also reducing to 80%. In tableau, i'm using .tde file to do my analysis and reports. However, ever month when new data comes Tableau is not allowing me to append/union new .tde file to existing .tde file.
how can this be done ?
