Design used the wrong characteristic value and wanted to change. So the correct one was put in and then chosen in the sales order. If you look at changes in va02 you can see where the new one was chosen.
After removing the old from a dependency and deleting the value in ct04 a pop up shows it is still used but only in class type 300 and not in any configurations (orders). You can still delete it despite the warning.
Executed RCUTABLEINFO for the sales order and it still shows the old value under IBSYMBOL for the atinn atnam.

looking at CAWN the value is not there of course as it was deleted on purpose in CT04.
So something is not committing in a sales order configuration object on change.
Is there a consistency check or cleanup for this?
