I can't share the screen shots however, I can try to elaborate a bit more, may be it help you to understand the scenario:
I am using the Weekly Calendar and Weekly timescale and week 22 as current period
In my Module A, I am using Time as a page selector (Week 22 selected), List 1 in rows and Line items in Columns .
there is a raw data storage Module (Module B) from where I am pulling the values in Module A. lets assume my current period is week 22 and when it is over then I need to change my current period to Week 23, to do this I will go to TIME and change the current period to Week 23, the moment i change it, my Week 22nd calculation gets 0 and I wanted to know how can I keep it.
Do I need to hard code my Week 22 values before changing the Current Period to Week 23 or is there any simple way for the same.
