          Hi,

           

          If I understood well, you can create a new calculation field using a cast like an integer or float depending of your values like INT([dimension])

          I attached an example.

           

          Regards,

            Hi Cristian,

             

            I the got the above numbers(in the screenshot) using the below calculation

             

            FLOAT(IF [Modality]='Daily' and [Segment]='B' then '133553'

            ELSEIF [Modality]='Monthly' and [Segment]='B' then '131076'

            ELSEIF [Modality]='2 Weekly' and [Segment]='B' then '145596'

            Else " "

            End

             

            Now I need in the Table to aggregate the B.B=133553+131076+145596

              Hi Cristian,

               

              Hope you are able to get my point.

               

              It is like to the current data base cube i am feeding in manual feeds by creating Calculated fields and then various calculations using those.

                Hi,

                 

                Not really, I think that your problem is around the data type, but is difficult to know without see a workbook.

                Can you provide an example Tableau workbook file?

                 

                I attached a new example with the formula that you give me, let me know if help you.

                 

                Regards,

                  HI Cristian,

                   

                  My data source is Cube file.Perhaps it is the reason Tableau is finding it difficult.

                    Sorry, I missed that the data-source is a Cube in your Friday comment.

                    I have a lot of problems also with Cubes with Tableau and I skipped with the following tricks that maybe help you:

                     

                    1. Create two data-sources, one from the cube and another from a basic Excel structure or CSV than can blend with a common fields.

                        To explain with more detail with Cubes you will have a lot of limitations like change the datatype for example, then that I did was in a blended data source with a costume data-source that I can define and handle, you can created a new field with the new data type and the only that you need to do is create the common structure that you expect in the cube to you can use it in the second custom data-source.

                     

                    2. Not connect directly with the cube, use a connector as intermediary like a Excel with a Pivot Table, a database T-SQL running a MDX like a procedure and saving the answer into a database, etc.

                    The idea here is when you are doing analysis then you need connect to the full cube to can explore and understand the data but when you are doing Dashboard you don't need it because you can normally limit the dimensions and his combinations to has a subset predefined in an extract. (Except with the distinct counts)

                     

                    3. Connect directly to the source of the cube.

                    If you can to skip all of this limitations always is good to connect to the source of the cube, I normally let as a last option because when I used a cube has internally MDX or DAX calculations than will be expensive/timeless to reproduce with SQL queries. If the cube is basic like is organizing the data in hierarchies or change names and datatypes and you can connect, is maybe your best option.

                     

                    If this solve your issues I will appreciate if you mark like a correct answer.

                     

                    Happy Viz!

                      Thanks Cristian for your suggestion!

                       

                      Before reading your suggestions had tried to create excel data source and blend but the metrics/measure which require simple addition does work good but when it requires advanced calculations and level of drilling it's feasibility is a question mark.

                       

                      Hence, I achieved my result by using LOD and feeding the data in the same created field.

                       

                      Thanks again and appreciate your efforts and time for me.

                       

                      Still would love to see Tableau experts come up with some solution while handling such kind of scenario.
