EC12 Error when Journal Import...

Hi all,
I has an issue when the Journal Import always bring up the Error EC12.
as long as we do the closing AP by running a query:

  select entered_dr, accounted_dr, entered_cr, accounted_cr
        from GL_INTERFACE
        where status = "EC12" and
        user_je_source_name = "Payables" and
        currency_code = 'USD'

then we do the update process

update GL_INTERFACE
set accounted_dr = entered_dr,
accounted_cr = entered_cr,
status = 'NEW'
where status = "EC12" and
user_je_source_name = "Payables" and
currency_code = 'USD'

problem can be completed and AP Period Closed.

My question, does this have to
