Duplicated data when run Crystal report

Question

Afternoon all,
I'm trying to create a report which compares quantity of sold goods and qty of orderd goods.
I've started just with one table for sold quantity using parameter fileds for From Date, To date, Customer and Part Number. I've ran the report and everything is OK.
When I add another table (and link the fields) to get ordered quantities and run the report I receive duplicate data for ordered goods.
To be more precise, I think that the duplicate data are in the rows where I have sold quantity but no ordered goods.
As for example:
Invoice Date   Inv. Qty             Date of ordered g.       Ordered Qty
7.6.2006        80                     9.6.2006                        160
9.6.2006        80                     12.6.2006                       160
11.6.2006      80                     12.6.2006                       160
The Sum formula then for Ordered qty gives 480 pcs, but it should be just 320.
I'm sorry, If you have already answered similar question. I was not able to find it.
Thank you in advance for your help.

Hi Branislav,
I think this is just because of dates in your Invoice Qty table. Do the following to create the report.
--Create report with Invoice and Order tables and use inner join to join the tables.
--Insert a group on Part Number and place the following fields on detail section
Inv_Date,Inv_Qty,Ord_DAte,Ord_Qty
Now your report looks like :
Invoice Date Inv. Qty Date of ordered g. Ordered Qty
7.6.2006 80 9.6.2006 160
9.6.2006 80 12.6.2006 160
11.6.2006 80 12.6.2006 160
Now right click on Order_date,Ord_Qty and format fields--click on suppress duplicated
Now your report looks like
Invoice Date Inv. Qty Date of ordered g. Ordered Qty
7.6.2006 80 9.6.2006 160
9.6.2006 80 12.6.2006 160
11.6.2006 80
Now to get summary on order_Qty Create a running total like
Right click on running totals--new give the nameSelect the Ord_Qty field to get total, Type of Summary should be sum
Evaluate--Click On change of field and select Order_DAte
Reset--Click On change of group.
Now place this running total in group footer under Order_Qty. This will solve issue.
Thanks,
