powerpivot - DAX partition/monthly totals -

-

i trying figure out how mimic sql partition in dax query. if using sql use similar this: 

sum([total units]) on (partition [fiscal month]) ttl_mth_unit

or 

,sum(case when 'order line item details'[no of transfers] = 1 'order line item details'[total units] end)) single  ,single/ sum('order line item details'[total units]) perct_single

my data looks this: 

fiscal month    transfer cnt    units  2017-apr            0            100 2017-apr            1            300

ideally results this:

fiscal month    0transfer   1transfer   %0     %1     ttl 2017-apr       100           300        .25    .75    400

or this: 

fiscal mon th   transfer cnt    units     %          ttl units 2017-apr           0              100   0.25        400 2017-apr            1             300   0.75        400

this dax code

evaluate( filter( addcolumns( summarize( 'order line details' ,'calendar'[fiscal month] ,'calendar'[fiscal year nbr] ,'order line item details'[no of transfers] ,"total units test",'order line item details'[total units] ), "month abbr", mid('calendar'[fiscal month],1,3) ,"month id", 'calendar'[fiscal year nbr]&"-"&mid('calendar'[fiscal month],1,3) ),  [fiscal year nbr]>(2015) ) )

i've tried using summarize , different variations of sumx either using wrong functions or not setting properly. 

calculate([total],datesmtd(date[calendardate]))

do not forget mark date table date table in tabular model, otherwise not wok. got me before.

i have postgresql db number of tables. if query: select column_name information_schema.columns table_name="my_table"; i list of columns returned properly. however, when query: select * "my_table"; i error: (programmingerror) relation "my_table" not exist 'select *\n "my_table"\n' {} any thoughts on why can columns, can't query table? goal able query table. you have include schema if isnt public one select * <schema>."my_table" or can change default schema show search_path; set search_path my_schema; check table schema here select * information_schema.columns for example if table on default schema public both works ok select * parroquias_region select * public.parroquias_region but sectors need specify schema select * map_update.sectores_point

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
