Here is my code, I use SAP B1 on SQL Server 2016.
SELECT
T0.[CANCELED], T0.[DocNum], T0.[DocDate], T0.[DocDueDate],
T0.[CardCode], T0.[CardName], T0.[DocTotal], T0.[PaidToDate],
T2.[DocDate],
MAX(T2.[DocDate]) AS LastPaymentDate,
CASE
WHEN T0.[PaidToDate] >= T0.[DocTotal] THEN 'Lunas'
WHEN T0.[PaidToDate] < T0.[DocTotal] THEN 'Belum Lunas'
END AS 'StatusPembayaran',
T3.[WhsCode],
CASE
WHEN T3.[WhsCode] = 'WH-OBRAL' THEN 'Harga Spesial'
ELSE 'Harga Normal'
END AS StatusHarga,
CASE
WHEN DATEDIFF(DAY,T0.DocDate,T0.DocDueDate) BETWEEN 0 AND 7 THEN T0.[DocDueDate] + 5
WHEN DATEDIFF(DAY,T0.DocDate,T0.DocDueDate) BETWEEN 8 AND 14 THEN T0.[DocDueDate] + 7
WHEN DATEDIFF(DAY,T0.DocDate,T0.DocDueDate) BETWEEN 15 AND 30 THEN T0.[DocDueDate] + 10
WHEN DATEDIFF(DAY,T0.DocDate,T0.DocDueDate) BETWEEN 31 AND 60 THEN T0.[DocDueDate] + 17
END AS MaxTolerance,
CASE
WHEN MaxTolerance <= LastPaymentDate THEN 'Safe'
ELSE 'Not Safe'
END AS 'PaymentCheck'
FROM
OINV T0
INNER JOIN
RCT2 T1 ON T0.[DocEntry] = T1.[DocEntry]
INNER JOIN
ORCT T2 ON T1.[DocNum] = T2.[DocEntry]
INNER JOIN
INV1 T3 ON T0.[DocEntry] = T3.[DocEntry]
GROUP BY
T0.[CANCELED], T0.[DocNum], T0.[DocDate], T0.[DocDueDate],
T0.[CardCode], T0.[CardName], T0.[DocTotal], T0.[PaidToDate],
T2.[DocDate], T3.[WhsCode]
ORDER BY
T0.[DocNum] DESC
I get this error:
Invalid column name 'MaxTolerance'
I already use [] on the MaksimalToleransi but it don't change anything. i want to check which record that MaxTolerance is less than or equal to LastPaymentDate
