Mapping a CASE constraint gives error:The expression is not properly formed

Question

Hi
I am hoping someone can help us with this as we cannot find it in the usual places:
I have the following WHERE clause in my query:
WHERE xd.cii_owner_account_id = hca.cust_account_id
AND incidentb.incident_status_id = incident_status.incident_status_id
AND incident_number = xd.sr_number
AND ( (CASE
WHEN buyout_immediate_flag <> 'Immediate'
THEN '-'
END) = '-'
OR (CASE
WHEN buyout_immediate_flag = 'Immediate'
THEN incident_status.NAME
END
) LIKE '%Authorised%'
OR (CASE
WHEN buyout_immediate_flag = 'Immediate'
THEN incident_status.NAME
END
) LIKE '%IT Appro%'
We are unsure how to map the CASE expression and where it is meant to go. Possibly in the join ? Or expression compaonent. Problem is that both do not allow for CASE statements.
Please advise.

Hi there
Please can you clarify this because I am unsure where the expression operator would go in my example. You see, the CASE is seperate for each part of my clause and the CASE is what gives the left hand side of the WHERE statement in each line whereas the right hand side is written outside of the CASE.
I hope you understand what I mean, if not let me know and I will try to clarify it for you.
Thanks
