Why is my query failing with SQLCODE = -420?

Can I get some help with this? I’ll copy the code as well as the error. I looked up the error code

(DB2 SQL Error: SQLCODE=-420, SQLSTATE=22018, SQLERRMC=BOOLEAN)

but I’m not understanding what doesn’t meet the requirements of the function? I’m just trying to pull these tables, rename ACH_ORIGINATION.DESCRIPTION when it meets certain requirements, and then filter out the ones that don’t meet the requirements. I also want to group by DESCRIPTION but I’d like to get this portion working first.

SELECT
    ACH_ORIGINATION.COMPANY_SERIAL,
    ACH_ORIGINATION.NAME,
    ACH_ORIGINATION.AMOUNT,
    ACH_ORIGINATION.NEXT_POSTING_DATE,
    CASE ACH_ORIGINATION.DESCRIPTION
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%J & J%' THEN 'J & J Electric'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%DeCleene%' THEN 'DeCleene'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Arab%' THEN 'Arab'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Clifford%' THEN 'Clifford Signs'
        ELSE 'Nothing'
    END AS DESCRIPTION
FROM
    CORE.ACH_ORIGINATION AS ACH_ORIGINATION
WHERE
    ACH_ORIGINATION.NEXT_POSTING_DATE IS NOT NULL AND
    DESCRIPTION <> 'Nothing'

Answer

Per comments, fix the CASE expression like this:

CASE    WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%J & J%' THEN 'J & J Electric'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%DeCleene%' THEN 'DeCleene'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Arab%' THEN 'Arab'
        WHEN ACH_ORIGINATION.DESCRIPTION LIKE '%Clifford%' THEN 'Clifford Signs'
        ELSE 'Nothing'
END AS DESCRIPTION
