On-premise transaction CJ20N has menu path 'Edit' → 'WBS element' → 'Investment programs' → 'Asset under construction' (AuC) in case of investment projects. The same functionality is expected in Fiori apps Project Builder and Project Control.
- SAP ERP Project System (PS)
- SAP S/4HANA Cloud
The navigation (from 'Edit' → 'WBS element' → 'Investment programs' → 'Asset under construction') is not available in cloud applications Project Builder and Project Control.
As an alternative for your requirement, app "Project Planning" can be used to see the ID's of the created AuC's even on lower level WBS-elements.
