In the screenshot displayed, you just configured the usage in CyberArk and want to update...

 A usage is a configuration that allows CyberArk to manage passwords for files, such as XML or INI files, that are stored on remote machines. A usage is associated with a parent account, which is the account that has access to the file. To update the password of a usage, the least intrusive way is to use the “sync” button on the usage’s details page. This will synchronize the password value between the Vault and the file, without changing the actual password. The “change” button will initiate a password change process by the CPM, which will generate a new random password for the usage and the file. The “reconcile” button will initiate a password reconcile process by the CPM, which will use a reconcile account to reset the password of the usage and the file to the value stored in the Vault. References: Usages, Manage passwords for usages
