In the GA constants currently PBCO is set to Y. Shouldn't an error come up warning that you are posting to a prior period?

The PBCO error is issued when you enter a GL date before the current period via data entry. No warning will be issued on the post. When PBCO is flagged to Y in the GA constants it will just post regardless of GL date.. If you set PBCO to N it will give you a hard error on the post.
