Looking compare data based on dates in SQL to then run in SSRS - sql

Question

HI
I have created a piece of sql below to allow me to compare if a customer had stock in a previous period or not, i need to show where the customer has stock in this period and not the last period
Simply i want to be able to run a report that only lists PERIOD3 CUSTOMER1, even if i specify dates which include periods 1 - 4
PERIOD1 CUSTOMER1
PERIOD2 NULL
PERIOD3 CUSTOMER1
PERIOD4 CUSTOMER1
I dont know how in a report to only bring back PERIOD3 CUSTOMER1 data, what is the best way to do this? in an SSRS report or in the original SQL which can then be added to a SSRS report
SELECT C43.ACCOUNT15_C43,
C43.RECODATE_C43,
SNAPSHOT.WORDREF1_C43,
CUSTOMER.NADNAME,
CUSTOMER.NADPOCODE,
CUSTOMER.ATTVALFROM_T10
FROM
(
SELECT ACCOUNT15_C43,
RECODATE_C43
FROM dbo.MBC430
GROUP BY
ACCOUNT15_C43,
RECODATE_C43
) AS C43
INNER JOIN
(
SELECT dbo.MAA930.ACCOUNT15_NAD,
dbo.MAA930.NADACCNO,
dbo.MAA930.NADNAME,
dbo.MAA930.NADPOCODE,
T10.ATTVALFROM_T10
FROM dbo.MAA930
LEFT OUTER JOIN
(
SELECT ACCOUNT15_T10,
CUSTOMERLONG_T10,
ATTVALFROM_T10
FROM
dbo.MBT100
WHERE ATTRIBCODE_T10 = 'CU1'
) AS T10
ON dbo.MAA930.ACCOUNT15_NAD = T10.ACCOUNT15_T10
AND dbo.MAA930.NADACCNO = T10.CUSTOMERLONG_T10
WHERE dbo.MAA930.NADSEQNO = '999'
AND dbo.MAA930.NADTYPE = '23'
) AS CUSTOMER
ON C43.ACCOUNT15_C43 = CUSTOMER.ACCOUNT15_NAD
LEFT OUTER JOIN
(
SELECT MBC430_1.RECODATE_C43,
MBC430_1.WORDREF1_C43
FROM dbo.MBB010
INNER JOIN dbo.MBC430 AS MBC430_1
ON dbo.MBB010.PARTNO = MBC430_1.PARTNO_C43
AND dbo.MBB010.ACCOUNT15 = MBC430_1.ACCOUNT15_C43
GROUP BY
dbo.MBB010.PRE_B01,
dbo.MBB010.PARTYPE,
MBC430_1.WORDREF1_C43,
MBC430_1.RECODATE_C43
HAVING dbo.MBB010.PRE_B01 = 'T'
AND dbo.MBB010.PARTYPE = 'FG'
AND NOT MBC430_1.WORDREF1_C43 = ' '
) AS SNAPSHOT
ON CUSTOMER.NADACCNO = SNAPSHOT.WORDREF1_C43
AND C43.RECODATE_C43 = SNAPSHOT.RECODATE_C43
Thanks
