Query fails in BI Pub but works in other interfaces

Question

I have a query that fails in BI Publisher with an 'ORA-00920: invalid relational operator' error but I drop the same query in toad and it works fine. I don't see an error but when one tool tells me something works and another tells me it doesn't, I tend to believe the one that works. There is a case statement in the where clause that seems to be the problem (see below). If I comment it out the query works in BI Pub. The case statement WORKS in Toad. I don't know how to troubleshoot a 'non-error' to make it work in in BI Publisher. Could it be a Toad thing?
where
o.orgpoint_nm in (:p_orgpoint_nm) and
i.inventory_status_desc in (:p_inventory_status) and
i.version_num in (:p_inventory_version) and
(case
when (:p_regulation_alt_nm) is not null and instr(lreg.regulation_alt_nm,(:p_regulation_alt_nm)) > 0
then 1
when (:p_regulation_alt_nm) is null and lreg.regulation_nm in (:p_regulation_nm)
then 1
end) = 1 AND
lreq.requirement_nm in (:p_requirement_nm) and
oi.effective_dt <= sysdate and etc.........

Answer 1

You could use the Word Page break and see if that works better..
