Help for a RPAS WB configuration

Hi,

I need help for below.

I want to show one measure in a WB in below way.

All measures have intersection day-item-str

1. Measure (meas1) will be visible in WB
2. It will be editable only once  current date>= RPAS_TODAY
3. Then I will go to one cell which meet above day cond and change the value in the measure
4. Then copy the measure to another measure (meas3) with above edited data

I tried things in below way but not know whether it'll work.

in WB calc group

meas1 = meas2  (meas1 and meas2 are same)

created a custom menu where a rule group was written as below
