If you need to change the process creation date, you can do the following:
1. Create an additional field for the process with the "Date and time" type.
2. Specify in this field the date you need, which should become the date the process was created.
3. At the stage of the business process, or at the procedure, set the action "Copy process fields", with which you copy the date from the additional field to the "Date of creation"
