Crystal Report: Display 0.00 for duplicate values

问题:

I am making a crystal report which displays values from database. Now the values from db contains duplicate values.

I need that duplicate values should be suppressed and should display 0.00

For Ex.

Value

• 250.00
• 250.00
• 250.00

Should display

• 250.00
• 0.00
• 0.00

I have applied "Suppress Duplicate" to the column but don't know how to display 0.00 there.

Thanks much!

Do not check Suppress if Duplicated.. You need to write formula for Display String.

For example,

if PreviousIsNull ({object.field}) then 
  cstr({object.field})
else
if CurrentFieldValue=previous({object.field}) then 
   '0.00' 
else 
  cstr({object.field})

EDIT:

  if PreviousIsNull ({object.field}) then 
      cstr({object.field})
    else
    if {object.field}=previous({object.field}) then 
       '0.00' 
    else 
      cstr({object.field})

Right click on Field and click on Format Object Then click on Customize button Then there is a "Show zero value as" with dropdown to Default. Select that dropdown value to 0 instead of default.
