When attempting to delete a user on the OnDemand portal, the following error is thrown:

When trying to activate this same user, the following error is thrown: 

 You have entered invalid data. Please try again. 

Release : 15.4.1

Component : CLARITY PPM SAAS OPERATIONS

These errors may occur if a user having the same username no longer exists in the Clarity instance that the portal user is assigned to. In order to be able to delete the user, a user having this username will need to be created in Clarity or if there is a user that had this username previously, their username will temporarily need to be changed back. Once a user having the same username as that defined in the portal, the user will be able to be deleted without error using the following steps: 

1. Un-assign user from all applications. This will send a XOG request to PPM to deactivate user in PPM. User will not be deleted in PPM.
2. Deactivate user in Portal
3. Remove user from Portal
