Annual Sales Comparison Analysis by Year - Query

Question

Hi,
I need some help please!
I need a query where I can compare sales to the previous year, preferably with manual date range entries.
CardCode u2013 CardName u2013 SalesX u2013 SalesY
Where the date range is the same but SalesY is for the corresponding time 1 year back.
I can get the individual totals for each year but I cannot get to combine the two years in one report.
Thanks.

Hi Desmond,
Sorry, just get spare time to read and reply your post.
I'm gonna give you explanation regarding your statement here "I notice that if I manualy type in a date in the date range and there is no posting on that date it will generate a blank report".
Unlike SQL stored procedure or function where you can pass any value to the passing parameter (as long as you pass appropriate data type), you have to pass value from certain table in B1 if you do the query in B1 query generator.
Thus, this following code:
DECLARE @DateFrom AS DATETIME
DECLARE @DateTo AS DATETIME
SELECT @DateFrom=DocDate FROM OINV T0 WHERE T0.DocDate='[%0]'
SELECT @DateTo=DocDate FROM OINV T1 WHERE T1.DocDate='[%1]'
You can't do something like this for instance (in B1 query generator case):
DECLARE @DateFrom AS DATETIME
DECLARE @DateTo AS DATETIME
SET @DateFrom='[%0]'
SET @DateTo='[%1]'
So, you need to select from certain table (I use OINV in this case) as a bait to contain the variable with a value.
Therefore, the reason you didn't get any result if you typed the data manually, it wasn't due to manual input / you choose the date from drop down. It was merely cause by the date which you entered manually doesn't have any record in OINV table. Make sense isn't it, it is as if you try to do the following query
SELECT @DateFrom=DocDate FROM OINV T0 WHERE T0.DocDate='1/1/2012'
where actually you don't have any record in OINV table with '1/1/2012' date.
So, you could change above code with this
DECLARE @DateFrom AS DATETIME
DECLARE @DateTo AS DATETIME
SELECT @DateFrom=RateDate FROM ORTT T0 WHERE T0.RateDate='[%0]'
SELECT @DateTo=RateDate FROM ORTT T1 WHERE T1.RateDate='[%1]'
or this
DECLARE @DateFrom AS DATETIME
DECLARE @DateTo AS DATETIME
SELECT @DateFrom=RefDate FROM OJDT T0 WHERE T0.RefDate='[%0]'
SELECT @DateTo=RefDate FROM OJDT T1 WHERE T1.RefDate='[%1]'
Because, logically, you should have much more date data in those two table (ORTT for daily exchange rate and OJDT for journal entry). It doesn't mean you want to retrieve data pertaining with exchange rate or journal entry, as I said in above, it serve only as a bait to fill your parameter @DateFrom and @DateTo used in your query logic with date value. The table itself doesn't matter.
Hope now you could understand the basic concept here.
