    Tableau file on HANA view basics

    Zeenat Goyal

      Hi All,

       

      I am trying to create a visualisation in tableau on top of HANA view. I would like to understand few very important things -

       

      1. whenever there is a change in the view level at backend (addition of a column, Input parameters/prompts) Tableau file is not getting the updated.

      2. Tableau is created from a HANA view in one package and later when the package is changed from the backend, how will I repoint my tableau file from Package 1 to package 2.

      3. How the tableau file will be one server to another i.e. from Dev to QA lets say.

       

      Thanks in advance.

          Hi Zeenat,

           

          Questions always will create new questions;)

           

          a. What kind of connection did you use? I assume a "Live" connections which reflects any change in HAHA after refresh in Tableau

          b. Re-point on latest package...something like a filter with max(packageID)

          c. Is your Tableau landscaped as a "mirror" against SAP HANA or are you using only one Tableau environment?

            Hello Norbert,

             

            Thanks for the quick response,

            1. Yes, connection is live but still I am facing problem in refreshing the structure , I am using Tableau Desktop 9.3.

            2. I am unable to understand how ? Here is my scenario , For personal development , there is one package XYZ , after some round of brain stroming with business once it is finalized it is moved to FINAL package in DEV environment.

            So , how will I repoint my tableau file from XYZ\HANA_View_1  to FINAL\HANA_VIEW_1

            3. Yes , tableau landscape is a mirror image against SAP HANA .

              Zeenat,

               

              The following.

               

              Concerning

              1. it's hard to tell what is going wrong. As said a "Live-connection" should reflect latest status in HANA.

              2. I assumed that your view contains a field "PackageID". I can't imagine, from the top of my head, a scenario where you will switch from view to the next view.

              3. Based on naming-conventions HANA-Views in DQ(A)P-landscape should be identical to recognized by Tableau mirrored applications.

                Thanks for the reply for point 3 Norbert

                I am still open with question 1 and 2 and most importantly  2.
