I am the administrator on our Concur site and we are a construction company. Employees must select which construction project their expense is related to while filling out their expense reports. I keep this list updated using the list management feature. Now that we have had SAP Concur for around a year, there are some finished projects that I would like to take off of the construction project list so that it does not keep growing. These projects are inactive and should never be used again.

If I delete the old projects out of this list, will it have an affect on the expense reports that were submitted in the past which were coded to the old projects I want to delete?

Or

Will those expense reports still be coded to the project they selected in the past and the employees just will not be able to see the old projects in our job list anymore going forward?
