    Cut the Incremental Refresh on the left

    Eugenia Makarova

      Hi all,

      My question sounds strange but describes the issue well, i hope:-)

      There is a huge incremental ds(30gb).

      But actually only 1/8 data(last N weeks data) is in use. If you ask me why Full Refresh is not there- the asnwer is that Full REfresh for N weeks will be a long running, not sure if it will finish at all.

      So i need exactly what is in the header - save somehow the accumulated info for last N weeks , and get rid of old data.  Ideally such "cut" should be done preiodically.

      I have the idea about such the trick using database, but was wondering if could be done purely by Tableau.

      Please advise.
