How to copy existing Crystal Reports to the project? This should not affect the changes to the original Crystal Reports.
I have a Crystal Reports at : E:\\DM A
Very Simple !!
Add a New Crystal Report from Visual Studio Project.
After adding a New Crystal Report, you can see a Dialog Box 'Crystal Report Gallery' (as shown the fig below)
Select 'From an Existing Report', and press OK.
Browse the Original Report which you want to duplicate.
Now your Clone or Duplicate Report is ready !
The changes in the reports won't affect each other....
Hope this ll help you. Leave comments if any.
you can not clone or copy one crystal report into another, instead you can use the same datatable which is assigned to the Invoice.rpt and generate a new crystal report with the datatable.
