To edit an existing label in iReport, you have to import the file using Specify first.
This is done using the same Resource Import/Export Tool you use to export the file.
Navigate first to the Resource Import/Export option in the System menu.
Click “My Resources”
Click on the Report Resources tab, then click on Add New Resource . Click Import .
Select the file you wish to import, and in this case, the label or report file.
Now you can press OK .
The label should be visible in your sidebar now under the Reports section!
The next time you open SpiReport you can click on the folder icon in the top left and you will see the imported report!
