SAP Ariba temporarily made the feature SM-32192: Enhancements to Summary area in supplier 360° profile to show Sourcing and Contracts data unavailable while addressing some technical issues. For those customers, the Business Activity area of the supplier 360° profile wasn't available, and in sites where the Sourcing or Contracts panels in the Summary area of the supplier 360° profile were enabled, those panels also weren't available.
Now, SAP Ariba has re-enabled this feature for all customers.
