Calculate Percent by Column Total DAX Measure

[njd_1988]

Hello, Power BI Community! 

I'm attempting to create a DAX measure that will calculate percent by column total that accounts for week over week data and a subgroup. I've been researching this for the past week and i'm unable to find a formula that works. Since i'm using a slicer to switch between different metrics, i'm unable to use the "show value as" feature. I've included the organization and some sample data below along with the column names below. Overall, i'm wanting to find week over week volume for the number of calls that come from specific states and cities. If I need to include any additional information, please let me know. Any help is greatly appreciated! Thanks!

Thanks for the reply, @amitchandak! I'll also keep the feedback in mind for any future posts. When using your code, results came in as 100% for everything. I was able to figured it out after doing a little more research. Below is what I used. Let me know if you have any feedback. 

CALC_SURVEY_VOLUME_WoW = DIVIDE(SUM('Table'[Call]),CALCULATE(SUM('Table'[Call]),ALLSELECTED('Table'[State], 'Table'[City])))

@njd_1988 , the subject and description not working together , if need % for a column say week ending date

% of week = divide(sum(Table[Call]) , calculate(sum(Table[Call]), filter(allselected(Table), Table[State] = max(Table[State]) && Table[City] = max(Table[City]) ) ) )
