I get weekly data and have to make report every week with MTD, QTD AND YTD on the same table. I have columns Start Date (Monday) and End Date (Sunday), month number, week number, year, quarter number and Dollars Sold and Units Sold of each product. I have the following query to get MTD inspired by other post:
SELECT b.month AS Month,
b.[Vendor Part] AS VendorID,
(SELECT sum(a.[Dollars_Sold]) FROM [DATA] AS a
WHERE a.Month<=b.Month
AND a.Year=b.Year
AND a.[Vendor Part]=b.[Vendor Part]) AS MTD_Dollars
FROM DATA AS b
GROUP BY [Vendor Part], Month, Year
When I try to run the query, the following dialog box pops out:
Please check the picture for dialog box
Vendor part is the unique ID of each product. Then after a long time waiting, the query will return a result only with totals for each month.
Does anyone know what is wrong? I don't want the dialog box out, I want the query to be able to produce a table with each product's MTD/QTD/YTD.
This query works for totals of each month, but not for each product in each month. Please help. Thank you.
