We have a few companies that have tested and noticed that if information in a contact changes, it will change the information in historical projects as well. Here is the situation that made me create the post. John Smith is a referring agent that works for Insurance Company #1 for the last 3 years and has referred 25 projects to the customer. He then changed jobs and now works for Insurance Company #2. Our customer wants to track how many referrals came from InsCo1 AS WELL AS John Smith while he worked at #1 and how many referrals from him now that he's employed by #2. Issue being now, once that contact info is changed, it now looks like Insurance Company #2 referred the 25 projects in the last 3 years. The work around is to create another contact for John Smith and add a variant, but that shouldn't be our permanent solution. I know that Luxor has a feature that allows for this type of change without feeding the new info back to historical projects, but it's been a LONG time since I have used Luxor and I don't remember how that function really works anymore.
