Crystal Reports -How to run totals

Hi,

I have a SQL Db. I am running crystal 9.

I want a simple report like this

Period : 1/1/2007 to 31/1/2007

Group #1 : Warehouse
 Group #2 : Product Code        
                                                              Opening:  Qty Value

    Details:  Doc. No.          Details.    In Quanitity   Value   Out Qty Value

Group #2 : fotter:                                 Closing : Qty Value

I have got the report formatted, sorted accordinly. The details part is not a proble. The opening and closing balances i have problems. Not getting results.  I have used formulas and various tricks. I have got parameters as input for the date from to.  But i am beaten. Need Help urgently.

What information is in the database?

Do you have a field that shows the currentqty or is this calculated based on a starting qty of 0 then change records added to show the changes?

Hi,

Ok. let me put it this way, The table has transactions for all months, say from Oct 2006 till date.
The fields  warehouse, itemcode,trdate, inqty,outqty,trvalue

Now I am using parameters to specify the fromdate and ToDate to determine the month of the report.
So if I specifiy say 1/1/2007 to 31/1/2007, then I need to have the OpBal= Opbal+Inqty-Outqty from Oct 2006  till 31st Dec 2006. This will be opening. Then I need to print the details where only the data between trdate >=fromdate And trdate <=ToDate.
Next is to have the total on the details for Inqty and outqty. Finally need the Closing qty and value.

You need to get the opening balance in someway.

One way to do this is through SQL and an SQL expression.

Another way would be to use a subreport in the group header that calculates the opening balance and returns that value to the main report using a shared variable.

The details section would show the information and calculate the closing balance

Another way would be to calculate in the main report but suppress the details until you get to the start date.

Thanks.

I have been trying to use formulas.

I have a formula called Op_Qty and have put it in the detail column.

WhilePrintingRecords;
If {OINM.DocDate} < DateTime({?FrmDt}) And {OINM.InQty} <> 0 Then
numbervar Op_qty_sum:= (Op_qty_sum+{OINM.InQty});
If {OINM.DocDate} < DateTime({?FrmDt}) And {OINM.OutQty} <> 0 Then
numbervar Op_qty_sum:= (Op_qty_sum-{OINM.OutQty})

The problem is when the group ie. the Itemcode changes, the Op_qty_sum does not get
initialized to Zero 0. If you could help me with this, I think my problem is sorted.

Try this

In the report header add a formula to declare the variables
WhilePrintingrecords;
Global NumberVar Op_qty_sum:= 0;

In the group header add a formula
WhilePrintingrecords;
Global NumberVar Op_qty_sum;
Op_qty_sum:= 0;
