Thanks Naveen for the quick response, i am currently using 10.4.0 tableau desktop version, so is it compatible with that version?
Secondly, when i downloaded i got this XpandIT_Writeback.trex file, so whats the next step, i mean how do i configure with my desktop version.
Its not compatible with 10.4 ,
you must have 2018.2 to get this
So, with my earlier Tableau versions, there is no way, i can implement the API?
