Warning Message with Open Period Update in AM

Hi,

We are on PSOFT 9.2 and closing AM period. On trying to set lag days ( begin lag= -6, first open = 11/25/2019; end lag= -6, last open= 12/25/2019), we are getting the following  warning message:

"Warning- Last Open Date 2019-12-25 for BU XXXX is later than last open date 2019-11-30 for GL BU XXXX. Press OK to Continue."

The GL period is still not open- last Open date 2019-11-30. Is the warning due to this ? Is it ok to continue with the SAVE and open the GL next month( first open 12/01/2019) ?

Thanks,

Debolina
