For a more complete answer, please provide sample data and/or screenshots of the data and your model.

Quick down and dirty method: create a calculated column in your date table for all weeks showing whether the week number is less than the current/incomplete week. This column will change every time the data is refreshed and use it as a flag to exclude dates in or after the current week number.

Is Weeknum less =
Var Thisweek = WEEKNUM(TODAY(),2)
Return
IF([WeekNumber]<Thisweek, 1, 0)

Calculate([WOS], [Is Weeknum less] = 1)

This is my
WoS_ST_new = DIVIDE([latest_week_Inventory],[13WeekAvgST_units])
latest_week_Inventory = CALCULATE([Total Inventory_Units],TOPN(1,Query1,Query1[Week]))

FY2019W01 to FY2019W37 (latest week),..
W37 is not complete week, now have to calculate the latest week inventory for W36? instead W7

Without sample data, this is still just guessing. Please provide sample data and/or screenshots if available. Try this. Keep your latest_week_Inventory measure, add my LatestWeekInventory measure, and create the NewWoS_ST_new measure. don't remove your existing measures, just add my two versions and see if the NewWoS_ST_new works for you.

LatestWeekInventory = CALCULATE([latest_week-Inventory], [Is Weeknum less0=1)

NEWWoS_ST_new = DIVIDE([LatestWeekInventory],[13WeekAvgST_units])

WoS_ST_new = DIVIDE([latest_week_Inventory],[13WeekAvgST_units])
latest_week_Inventory = CALCULATE([Total Inventory_Units],TOPN(1,Query1,Query1[Week]))
