Hello All , 

Whenever i try to close my point of sale session i get this error :

ValidateError

Field(s) `date` failed against a constraint: The date of your Journal Entry is not in the defined period! You should change the date or remove this constraint from the journal

I have checked the date set against the fiscal tear set and it is included in that range.
