PTC_WM_CREATED_ON value changes upon modification?!?

[sjohnson-3]

Does anybody use PTC_WM_CREATED_ON on their drawing formats or otherwise? What's the difference between it and PTC_WM_MODIFIED_ON?
We use the former on our formats as a the initial creation date in conjunction with created by, and it was just brought to my attention that the date changes upon modification and check in of the object. Doesn't seem like it should work like that - isn't that what PTC_WM_MODIFIED_ON should be for?

PTC_WM_CREATED_ON tracks the creation date of each REVISION (first check in and each successive REVISE).

PTC_WM_MODIFIED_ON tracks the creation date (check in) of each ITERATION.

Thanks Tom!

By the way, I believe the behavior is the same for PTC_WM_CREATED_BY and PTC_WM_MODIFIED_BY. The first tracks the revision creator and the second tracks the iteration (version) creator.

There is no out of the box way to retrieve the very first, original creator and original creation date in Creo after an object has been revised. If you want to store this information permanently you will need to create custom parameters and manually populate them (or having some custom relations that populate them when empty).

Yes, that would be great if you could share your relations. Thanks!
