I created the line item in SYS00 & 01 as mentioned in the requirement below. I am confused with the requirement mentioning not showing HY value until all weeks are checked. Please help.
You should read the passage very carefully.
Here you need to understand the particular sentence "USER Selects a month".
You need to understand whether formula is needed or not.
Also this statement clearly states when a user inputs in month dimension module then it should reflect in week dimension module.
This statement says you have to study about summary type for boolean(ANY/ALL)
All the best
