Is it possible to modify historic process instance data?

I've received a request to be able to modify process variables on completed process instances. A common scenario is that a user somewhere along the workflow has filled in a field incorrectly and it was not caught immediately- long after the instance is dead and buried, someone looking at reports mig

Hi,

There is not API to change HistoryService data. The purpose of HistoryService is to provide the data which were present at the time when process instance was executed (e.g logs auditrail…).
I can agree that values can change in time. I would suggest to do not store such a information in a process.

Martin

Unfortunately we're using Activiti in Alfresco so we're kind of bound to use process variables in that manner- there's not really a whole ton of leeway in how we store our data. There's always the opportunity to sidecar the information in a contentless object or something of that nature, but then the metadata is not easily accessible from Alfresco's Workflow Details page.

Thanks for your feedback nevertheless though.
