Why?  What are you trying to do?

I would like to get the status period lock for spesific module

but i found that if all period is lock or unlock for all month and all module, the lock status was 1 

but when there is one period is open and other was lock, the status change to 1 or 0

can you please help me for this case? because my data became not accurate when i check the period last year is lock or not when the all period is all lock
