Project Manager Mandatory...for changing Project Status to Approved

Hi

Am I correct in saying that from system perspective only Projects defined with class of Contract has requirement to have Project Manager as Mandatory Key Member on the Project.

For Project defined with class of Capital and Indirect Project, there is no system requirement to have Project Manager. We understand that we can specify if Project Manager is required filed as part of the Project Creation by making it Mandatory in the Project Setup Quick Entry.

We are able to change Project Status from Unapproved to Approved using status change button on Project defined with Capital and Indirect Project Class.
