How many days old process history we can see in Tridion workflow management tab

Question

How many days old process history we can see in Tridion workflow management tab as shown in below diagram

Can somebody point me to some documentation for this.

Answer 1

By default Tridion keeps all Workflow process history in its database, so you will have access to all processes created since the "beginning of times".

You can purge all processes which occurred before a certain date using the Remove-TcmProcessHistories PowerShell command. See Documentation.
