posting problem when update axapta 3.0 to sp6

Hello,

Currently I patched the sp6 to our axapta 3.0 sp3.I got the following Infolog

   Field 'Parameter ID' must be filled in.

I debuged the system and found that it catch an exception when run the following method returned false:

static boolean  exist(Num  parmId)
{
    if (parmId)
    {
        return (select firstonly recId from salesParmUpdate
                    index hint ParmIdIdx
                    where salesParmUpdate.parmId == parmId
               ).recId != 0;
    }
    return false;
}
