Hello,
I have 2 tables in 1 table(KEKO) I have 2 fields of intrest: MaterialID and VaildDate in which I need to capture the MaterialID with the MAX ValidDate:

SELECT MaterialID, MAX(VaildDate) AS CurrrentPricePeriod
FROM KEKO
GROUP BY MaterialID

That all works great. But I need to join those results to another table(CKIS) where they would be joined by the MAX(ValidDate) and MaterialID.

SELECT * FROM CKIS C
JOIN (
SELECT MaterialID, MAX(VaildDate) AS CurrrentPricePeriod
FROM KEKO
GROUP BY MaterialID) AS XXX
ON XXX.Current_PricePeriod = c.dtKey
AND xxx.material_id = c.Material_id
