customize tcode 223
I have been tasked with adding four fields to the report displayed when a user executes transaction c223. I have a few questions...Can I just copy the source code associated with tcode c223, rename it zc223 and add my fields to the custom report? What problems might I encounter if I use this approach? How will future updates to tcode c223 impact my custom report? What would be the best way to approach this development effort aside from the solution I propose above?
