Updating SQL Server based on unique row using WHILE LOOP - sql

Question

I'm trying to update my table using WHILE LOOP, unfortunately, instead of updating it based on employeeidno, it gathers all the total aremployee in all employeeidno and then update the row of all employeeidno based on it.
Is there a way to segregate the SET #aremployee based on employeeidno?
What I basically what for this query is that for every WHILE LOOP it will capture the data gathered, and then add it to the next loop, but is based on employeeidno.
DECLARE #cnt INT = 0;
DECLARE #aremployee FLOAT = 0;
WHILE #cnt <= (SELECT TOP 1 RIGHT(accountcode,2) FROM accounting_tblearningsamendmentaccount_db WHERE LEFT(accountcode,2) = '02' AND approvedby IS NOT NULL ORDER BY accountcode DESC)
BEGIN
SET #cnt = #cnt + 1;
UPDATE accounting_tblpayroll_db
SET #aremployee = #aremployee + x.aremployee,
accounting_tblpayroll_db.aremployee = #aremployee
FROM (SELECT
MAX(RTRIM(LTRIM(employeeidno))) AS 'employeeidno',
SUM(debit) AS 'aremployee',
MAX(accountcode) as 'accountcode',
MAX(RTRIM(LTRIM(referenceno))) AS 'referenceno',
MAX(RTRIM(LTRIM(particulars))) AS 'particulars',
MAX(RTRIM(LTRIM(postedby))) AS 'postedby',
MAX(RTRIM(LTRIM(approvedby))) AS 'approvedby',
MAX(RTRIM(LTRIM(notedby))) AS 'notedby'
FROM accounting_tblearningsamendment_db WHERE LEFT(accountcode,2) = LEFT('02000',2)
AND accountcode != '02001' AND accountcode != '02002'
AND payrolldue is null AND datedue BETWEEN '2020-10-06' AND '2020-10-20'
AND accountcode = CONCAT('020', CONCAT(CASE WHEN #cnt < 10 THEN '0' ELSE '' END , #cnt))
GROUP BY employeeidno) AS x
WHERE x.employeeidno = accounting_tblpayroll_db.employeeidno
AND x.aremployee <
(((accounting_tblpayroll_db.cutoffpay + accounting_tblpayroll_db.leave + accounting_tblpayroll_db.nightdifferential + accounting_tblpayroll_db.regularholiday + accounting_tblpayroll_db.specialholiday + accounting_tblpayroll_db.additionalincome + accounting_tblpayroll_db.overtime
+ accounting_tblpayroll_db.apemployee + accounting_tblpayroll_db.thmonth + accounting_tblpayroll_db.christmasbonus + accounting_tblpayroll_db.administrativeallowance + accounting_tblpayroll_db.supervisoryallowance
+ accounting_tblpayroll_db.hazardallowance + accounting_tblpayroll_db.shortageallowance + accounting_tblpayroll_db.licenseallowance + accounting_tblpayroll_db.transportationallowance + loyaltyincentiveallowance - '1000.00'
)
- (accounting_tblpayroll_db.sss_ee + accounting_tblpayroll_db.med_ee + accounting_tblpayroll_db.pagibig_ee + accounting_tblpayroll_db.late + accounting_tblpayroll_db.undertime)))
AND accounting_tblpayroll_db.datefrom = '2020-10-06'
AND accounting_tblpayroll_db.dateto = '2020-10-20';
END;
Thank you in advance.
Edit:
This is the simplified version:
DROP TABLE #temtable1;
DROP TABLE #temtable2;
CREATE TABLE #temtable1
(
referenceno int,
employeeid varchar(10),
ccode varchar(10),
amount float(10)
);
INSERT INTO #temtable1
(referenceno,employeeid,ccode,amount)
VALUES('1001','2001','3001','11000.00');
INSERT INTO #temtable1
(referenceno,employeeid,ccode,amount)
VALUES('1003','2002','3002','11000.00');
INSERT INTO #temtable1
(referenceno,employeeid,ccode,amount)
VALUES('1005','2003','3003','11000.00');
INSERT INTO #temtable1
(referenceno,employeeid,ccode,amount)
VALUES('1001','2001','3004','10000.00');
INSERT INTO #temtable1
(referenceno,employeeid,ccode,amount)
VALUES('1003','2002','3005','10000.00');
INSERT INTO #temtable1
(referenceno,employeeid,ccode,amount)
VALUES('1005','2003','3006','10000.00');
CREATE TABLE #temtable2
(
referenceno int,
employeeid varchar(10),
total float(10)
);
INSERT INTO #temtable2
(referenceno,employeeid,total)
VALUES('1001','2001',NULL);
INSERT INTO #temtable2
(referenceno,employeeid,total)
VALUES('1002','2002',NULL);
INSERT INTO #temtable2
(referenceno,employeeid,total)
VALUES('1003','2003',NULL);
DECLARE #cnt INT = 0;
DECLARE #total INT = 0;
WHILE #cnt <= 10
BEGIN
SET #cnt = #cnt + 1;
UPDATE #temtable2
SET #total = #total + x1.amount,
total = #total
FROM(SELECT
MAX(referenceno) as referenceno,
MAX(employeeid) as employeeid,
ccode as ccode,
SUM(amount) as amount
FROM #temtable1
WHERE
ccode = CONCAT('30', CONCAT(CASE WHEN #cnt < 10 THEN '0' ELSE '' END , #cnt))
GROUP BY
employeeid,ccode) AS x1
WHERE x1.employeeid = #temtable2.employeeid
AND x1.amount < 25000
END
select * from #temtable2
Current Result:
Expected Result:
What I intend for this is that the query will loop and add all code that starts with 3, depending on what employeeid the data is under.
The query will the first loop starting 3001, then up to 3010, and add it consecutively until it will not exceed 25000, but it's on every employeeid.
