statistical key figures in network header

dear all,

what might be the reason for Tab page Statistical Key Figures not bering displayed at Network header level?

SAP Help portal PS S/4HANA reads as follows:

• In Customizing for the Project System under

  Project System Tab Page: Activate Statistical Key Figures

  you can show an additional tab page in the Project Builder to edit statistical key figures for the following PS objects:

  • WBS element

  • Network

  • Network activity

  • Network activity element

I’ve activated all 4 objects but I see no new tab page at Network header. I’ve assigned new SKF to one of the network activities, but it doesn’t make a difference.

This is not the case of 2736606 (Activity missing from IMG), so I might have overlooked something else?

Thank you,

Marna
