To change text on a report (printout), you must first activated the "Pause Reports for Translation" setting in the Setup | Quote/Job Defaults | Print/Email Settings section. Then go to print the report with the text you want to translate, click Yes when asked if you want to Translate the Report. You can then do the same steps as above in the report as the window.
If you want to change the way data is formatted (presented) in windows or reports, then you can also translate the format picture to the one you would like. This is most useful for currency or date formating. There are 2 ways that Veculim formats pictures, so you need to translate both.
You can use the same system to change the currency symbol displayed in Veculim. Simply "translate" ~R~ to (for example) ~$~ in order to display values with the $ currency symbol.
