Adding new data to data source for Letter
I have a complex Letter template . I want to add some new customer data to my Excel data source, but the template does not include the new data, even if I save it again. It's not practical to re-create the letter template each time new customer data sets arrive.
Am I doing something wrong or is that functionality not available?
If it is not available, are there any work-arounds?
Any help would be appreciated.
