Check PTFs currency (up-to-date-ness)

Hello guys

For some years I use the following SQLs to check if my Group PTFs are
current

Select Row_Number() over (ORDER BY PTF_GROUP_CURRENCY DESC, PTF_GROUP_ID
ASC) as "Row #",
PTF_GROUP_CURRENCY, PTF_GROUP_ID,
PTF_GROUP_TITLE, PTF_GROUP_LEVEL_INSTALLED,
PTF_GROUP_LEVEL_AVAILABLE,PTF_GROUP_LAST_UPDATED_BY_IBM,
PTF_GROUP_RELEASE, PTF_GROUP_STATUS_ON_SYSTEM
From SYSTOOLS.GROUP_PTF_CURRENCY


with ilevel (iversion, irelease) as (
select os_version, os_release
from sysibmadm.env_sys_info
)
select Row_Number() over (Order by ptf_group_level_available -
ptf_group_level_installed desc, ptf_group_id) as "Row #", p.*
from ilevel, systools.group_ptf_currency p
where ptf_group_release = 'R' concat iversion concat irelease concat '0'
order by "Row #"



but recently I get a confusing (to me) error:

Query cannot be run. See lower level messages
