Hi&nbsp;vjnvinod,&nbsp;Use this formula to create your new DAX Table:NewColumn =GROUPBY ( Inbound; Inbound[AccountSector]; "TERFYTD USD"; SUMX ( CURRENTGROUP (); Inbound[TER_FYTD_USD] ))Regards.

Hey,&nbsp;as&nbsp;Anonymous already presented a correct answer using GROUPBY(), I just want to add some additional information about this function https://www.sqlbi.com/articles/nested-grouping-using-groupby-vs-summarize/ and here the official documentation https://msdn.microsoft.com/en-us/query-bi/dax/groupby-function-dax&nbsp;But if you do not need GROUPBY you should consider to use SUMMARIZECOLUMNS() instead https://msdn.microsoft.com/en-us/query-bi/dax/summarizecolumns-function-dax) or still SUMMARIZE, because it's much more performant.The DAX statement using SUMMARIZECOLUMNS:Table using SUMMARIZECOLUMNS = 
SUMMARIZECOLUMNS( 
   'Inbound'[Account Sector],"new column", SUM('Inbound'[TERFYTD USD])
)
 The perfomance aspect is described in a new DAX book that you will find here:&nbsp;https://www.amazon.com/Beginning-DAX-Power-BI-Intelligence/dp/1484234766/ref=sr_1_1?ie=UTF8&amp;qid=1526070538&amp;sr=8-1&amp;keywords=beginning+dax+with+power+bi by me fellow datanaut&nbsp;Phil_Seamark&nbsp;Here is the DAX statement using ADDCOLUMNS(SUMMARIZE(...Table using ADDCOLUMN SUMMARIZE = 
ADDCOLUMNS(
    SUMMARIZE(
        'Inbound'
        ,'Inbound'[Account Sector]
    )
    ,"Wrong Result", SUM('Inbound'[TERFYTD USD])
    ,"Correct Result", CALCULATE(SUM('Inbound'[TERFYTD USD]))
) There is also a great article on sqlbi.com coparing SUMMARIZE and SUMMARIZECOLUMNS:&nbsp;https://www.sqlbi.com/articles/introducing-summarizecolumns/&nbsp;Hope this gets you started&nbsp;RegardsTom

TomMartens&nbsp;This is really helpful, thanks for sharing this information.Despite creating this new table and relationship, my data doesn't interacts with each other, not sure why.

Hey,&nbsp;wondering what you mean by "doesn't" interact.&nbsp;I guess this means that there is&nbsp;more than table involved and/or there are slicers.&nbsp;From your post I deduct that you try to "relate" the tables, your original one and the one created by one of the DAX statements. This won't work, due to the design of the Power BI Model.&nbsp;&nbsp;Ideally you create a pbix with sample data that helps to recreate your issue, upload this pbix file to onedrive or dropbox and share the link.&nbsp;And it would also be helpful to describe in more detail what doesn't work.&nbsp;RegardsTom

&nbsp;TomMartens&nbsp;Hi Tom,&nbsp;sample small datasethttps://www.dropbox.com/s/87mgmsb7u70jloe/Testcheckdale.pbix?dl=0when the regions are filtered at "all" level, the interaction works perfectly fine (see&nbsp;above snapshot) , which is what my expected result should be (that means my outbound is interacting with inbound, pie and the table)&nbsp;Now whats happening is when i filter for any region let say Northeast and then click on other outbound americas, i am not getting the above model results (refer below screenshot), (highligting in red means, they are not interacting with Outbound values) &amp; the numbers of Pie and matrix are not in sync(i am fine with inbound, it may match or maynot)&nbsp;&nbsp;let me know, why my model is not working?
