Manage Business Configuration UI (BCUI) is locked.
"Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental."
To unlock the BCUI, you can go to Manage Data and select the Object Type "ActivityListObject" and object "root".
Set the field "locked" to "No" and Save.
If the issue does not get resolved by this, please ask your implementation partner or support to verify if the job "Synchronize Business Configuration" is in Submitted state in Provisioning.
