Is there anyway using the base system to change a dimension from Department to Purpose?

We have a dimension “Travel” with a dimension code of “Department”. Sometime in the last month it was changed to a “Purpose”. I have confirmed the RecId from a month old system and it has actually been changed somehow. We have no custom code around it, so it makes me think a user somehow did it with the base system, but I can’t figure out any way for it to be possible.

Any ideas?

If you mean the code reference they can right mouse click on it and selct record info and rename.
