Suppress if duplicated makes error in total on CR 8.0

Unfortunately I believe that is the way CR was designed.

One way to solve this may be to SELET DISTINCT records.

mlmcc

mlmcc can work in the sense that the whole line do not want to display , BUT I am assumeing only this duplicate not diplay and calculate , others column in this line still displaying

Actually my report comes out from three table

table_Alldates
Dates, product_ID
table_Sale
dates , saleQTY ,product_ID
table_Purchase
dates, PurchaseQTy,product_ID

and may be in sale or purchase on one date two transitions take plce and then if I want to print prduct transitions like

date , saleQTY ,PurchaseQTY, it make duplicate values in report
querry looks like this
____________________________________
SELECT Alldates.Dates, Alldates.Product_ID, table_Purchase.purchaseQTY, Table_Sale.SaleQTY
FROM (Alldates LEFT JOIN table_Purchase ON (Alldates.Product_ID = table_Purchase.Priduct_ID) AND (Alldates.Dates = table_Purchase.Dates)) LEFT JOIN Table_Sale ON (Alldates.Product_ID = Table_Sale.Priduct_ID) AND (Alldates.Dates = Table_Sale.Dates);

this is demo to illustrate real problem

I think Mr MsLim's comments to make a formula field may work.

Yes , My way is working BUT look like very funny
based on your report reqirement
some things in my mind.
a) are you printing a list of all record in a period of date ? or
b) are you printing based on unique of date ?
if a is yes , then if duplicate of quantity do not count , how the report can show the right sum of total .
if b is yes , then you must print out the sumof sale and purchase on such date , do not to show detail , BUT one more thing is if still having duplicate , and do not show up how should the report show right figure of sum ?
Normally , people using duplicate is as below
date , prod id , sale_qty , pur_qty
if the date is same BUT prod ID is different , then date will be invisble so that you will not see too much things.

A is yes.

 I want to print all transition of a product in

Product name(id) (group field)
date | saleQTY| PurchaseQTY

and data was as
for dale table
date    | product_ID | QTY
5-5-03 |1               | 50
5-5-03|1                | 20

for Purchase table
date | Product_Id | QTY
5-5-03 | 1           |25
6-5-03| 1            |15

the rusults looks like
Prodct 1
______________________________
date      |Sale qty | Purchase QTY
5-5-03 |  50        | 25
5-5-03 |  20        | 25 (duplicate)
6-5-03 |  15        | Nill or 0
               

My way can be working in the sense that no duplicate purchase qty on the same date , if there is same qty on the same date but under different PO , then this will will causing wrong figure of sum.
if this is to match the date , and sales is from which po qty , then it will be work , but is better to put in sales invoice and PO Number, so that easy to understand and trace.
for my suggestion , this report is very dangerous , due to if happenning same sales qty but under different sales invoice , also will causing incorrect figure to sum up sales qty.
How about is it possible happenning of sales qty from 2 po qty ?
all the above must consider for doing report also
