Wrap CTE inside another Select statement - sql

Question

Is it possible to wrap a CTE inside of another Select statement?
Here is my CTE:
WITH IRS AS
(SELECT BUSINESS_UNIT, VOUCHER_ID, VOUCHER_LINE_NUM, WTHD_ENTITY, WTHD_TYPE, WTHD_CLASS
FROM PS_VCHR_LINE_WTHD
WHERE WTHD_ENTITY = 'IRS' ) ,
PA AS
(SELECT BUSINESS_UNIT, VOUCHER_ID, VOUCHER_LINE_NUM, WTHD_ENTITY, WTHD_TYPE, WTHD_CLASS
FROM PS_VCHR_LINE_WTHD
WHERE WTHD_ENTITY = 'PA' )
SELECT IRS_WTHD.BUSINESS_UNIT, IRS_WTHD.VOUCHER_ID, IRS_WTHD.VOUCHER_LINE_NUM,
--COLUMN 1 TO BE USED IN MAIN QUERY:
CASE WHEN PA_WTHD.WTHD_ENTITY = 'PA' THEN 'PA'
WHEN IRS_WTHD.WTHD_ENTITY = 'IRS'
AND IRS_WTHD.WTHD_TYPE = '1099N'
AND IRS_WTHD.WTHD_CLASS = '01' THEN 'IRS'
WHEN IRS_WTHD.WTHD_ENTITY = 'IRS'
AND IRS_WTHD.WTHD_TYPE = '1099'
AND IRS_WTHD.WTHD_CLASS = '07' THEN 'IRS'
ELSE ''
END ,
--COLUMN 2 TO BE USED IN MAIN QUERY:
CASE WHEN PA_WTHD.WTHD_ENTITY = 'PA' THEN CAST(REPLACE(LTRIM(REPLACE(IRS_WTHD.WTHD_CLASS, '0', ' ')), ' ','0') AS VARCHAR)
WHEN IRS_WTHD.WTHD_ENTITY = 'IRS'
AND IRS_WTHD.WTHD_TYPE = '1099N'
AND IRS_WTHD.WTHD_CLASS = '01' THEN 'MISC' + CAST(REPLACE(LTRIM(REPLACE(IRS_WTHD.WTHD_CLASS, '0', ' ')), ' ', '0') AS VARCHAR)
WHEN IRS_WTHD.WTHD_ENTITY = 'IRS'
AND IRS_WTHD.WTHD_TYPE = '1099'
AND IRS_WTHD.WTHD_CLASS = '07' THEN 'MISC7'
WHEN PA_WTHD.WTHD_ENTITY = '' THEN ''
ELSE 'MISC' + CAST(REPLACE(LTRIM(REPLACE(IRS_WTHD.WTHD_CLASS, '0', ' ')), ' ', '0') AS VARCHAR)
END
FROM IRS IRS_WTHD
LEFT JOIN PA PA_WTHD ON PA_WTHD.BUSINESS_UNIT = IRS_WTHD.BUSINESS_UNIT AND PA_WTHD.VOUCHER_ID = IRS_WTHD.VOUCHER_ID AND PA_WTHD.VOUCHER_LINE_NUM = IRS_WTHD.VOUCHER_LINE_NUM
I would like to wrap the above CTE inside of this main SQL Select statement below and output the two CASE statement columns above into the final SELECT statement below while joining on BUSINESS_UNIT, VOUCHER_ID, and VOUCHER_LINE_NUM fields from the PS_VCHR_LINE_WTHD table :
--Main Select Statement:
SELECT CONCAT(A.BUSINESS_UNIT,A.VOUCHER_ID) AS INVOICE_ID, A.VOUCHER_LINE_NUM,
CASE WHEN EXISTS (SELECT 1 FROM PS_DISTRIB_LINE
WHERE BUSINESS_UNIT = A.BUSINESS_UNIT
AND VOUCHER_ID = A.VOUCHER_ID
AND VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM)
THEN 'ITEM' ELSE 'MISCELLANEOUS' END, A.MERCHANDISE_AMT, B.QTY_VCHR, A.UNIT_PRICE, A.UNIT_OF_MEASURE, A.DESCR, A.PO_ID, A.LINE_NBR,
A.SCHED_NBR, B.PO_DIST_LINE_NUM, A.DESCR254_MIXED, '','',
F.OR_ENTITY + '.' + F.OR_LOCATION + '.' + CASE WHEN B.BUSINESS_UNIT_GL IN ('90000', '90032', '90059') AND H.DEPTID = '741' THEN H.COST_CENTER
WHEN B.BUSINESS_UNIT_GL = '90000' AND H.DEPTID = '956' THEN H.COST_CENTER
WHEN B.DEPTID IN ('882', '883', '884', '885', '886', '803' , '887', '888') THEN '676'
ELSE '000' END
+ '.' + B.ACCOUNT + '.' + ISNULL(G.ORACLE_PROJECT_CODE,'000000000.') + ISNULL(NULLIF(B.AFFILIATE, ''), '00000.') + '.000000.' + '000000' ,'', C.ACCOUNTING_DT, '',
'','','', ISNULL(D.WTHD_ENTITY,''), '', '', '', A.SALETX_AMT
FROM PS_VOUCHER_LINE A
LEFT OUTER JOIN PS_DISTRIB_LINE B ON B.BUSINESS_UNIT = A.BUSINESS_UNIT AND B.VOUCHER_ID = A.VOUCHER_ID AND B.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM
LEFT OUTER JOIN PS_VOUCHER C ON C.BUSINESS_UNIT = A.BUSINESS_UNIT AND C.VOUCHER_ID = A.VOUCHER_ID
LEFT OUTER JOIN PS_VCHR_LINE_WTHD D ON D.BUSINESS_UNIT = A.BUSINESS_UNIT AND D.VOUCHER_ID = A.VOUCHER_ID AND D.VOUCHER_LINE_NUM = A.VOUCHER_LINE_NUM
LEFT OUTER JOIN PS_VENDOR E ON E.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND E.VENDOR_ID = A.VENDOR_ID
LEFT OUTER JOIN #CloudXWalk F ON F.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND (F.DEPTID = 'All' OR F.DEPTID = B.DEPTID)
LEFT OUTER JOIN #CloudCostCenter H ON H.BUSINESS_UNIT = B.BUSINESS_UNIT_GL AND H.DEPTID = B.DEPTID
LEFT OUTER JOIN #CloudProjectCodes G ON G.PS_PROJECT_CODE = B.PROJECT_ID
LEFT OUTER JOIN PS_PYMNT_VCHR_XREF I ON I.BUSINESS_UNIT = A.BUSINESS_UNIT AND I.VOUCHER_ID = A.VOUCHER_ID
WHERE C.INVOICE_DT > '01-03-2019'
AND I.PYMNT_ID = ''
AND C.CLOSE_STATUS <> 'C'
AND C.ENTRY_STATUS <> 'X'
ORDER BY 1,2
Is this possible, or is there an alternate way of avoiding using the CTE? I am using the CTE because I need to be able to run Case statements across multiple rows and possibly return data on other rows.
