Since the upgrade to SAP S/4HANA Cloud release 2202 you are no longer able to use app Project Builder (CJ20N)
- SAP S/4HANA Cloud 2202 and subsequent releases
Project Builder app is deprecated in 2202.
Instead of Project Builder use apps Project Control and Project Planning to maintain your project structures. These apps which have been available over 2 years provide a more consistent user experience for setting up and managing project structures for enterprise projects. Among other things, these apps come with a seamless forward navigation to other apps and a full support of the custom field framework in SAP S/4HANA Cloud.
SAP Blog https://blogs.sap.com/2021/11/26/removal-of-project-builder-with-sap-s-4hana-cloud-2202/ has more information on how to use the Project Control and Project Planning apps.
