Failure running glcal.odf as part of the R12 upgrade

Hi, I'm upgrading from 11.5.9.2 to 12.1.1.  While running the upgrade driver (6678700 merged with preinstall patches), one of the jobs fails while running file glcal.odf:

*******************************************************
In table GL_PERIOD_STATUSES, the column QUARTER_NUM
   is nullable when it should be not null.

Updating the column using the default value :

'SELECT p.quarter_num FROM   gl_periods p, gl_sets_of_books sob WHERE
p.period_name = GL_PERIOD_STATUSES.period_name AND    p.period_set_name =
sob.period_set_name AND    sob.set_of_books_id =
GL_PERIOD_STATUSES.set_of_books_id '

The fetch statement is:
SELECT ROWID FROM GL.GL_PERIOD_STATUSES WHERE QUARTER_NUM is null
