Edit process parameters from UI

I have two global variables that i want to set in my process, the only way I found to do that is with parameters but I couldn't find how to edit these data ( my admin must be able to edit them from an application page)

 I looked into process variables but the data is deleted after the process instance ends 

Any ideas on how i can create global variables that can be edited from the UI and doesn't get deleted ? 

Hi,

In order to update a parameter value at runtime you’ll need to use the enterprise edition. Another solution would be to use a business object and a business variable to store this data. Their lifecycle is decoupled from process instances.
