Hi I have the same issue since nearly 4-5 days (everything worked fine until then)
What I tested so far and received same error....
Tenant = T
Environment in Tenant = E
T1 E1 --> T2 E1
T1 E1 --> T3 E1
T2 E1 --> T1 E1
T2 E1 --> T3 E1
T3 E1 --> T1 E1
T1 E1 --> T1 E2
T1 E2 --> T1 E1
After having the issue with a more complex solution (1 Canvas App, 9 Custom CDS Entities, 2 Security Roles) quickly created a new solution (in T1,2,3), just including 1 all new canvas app with 2 labels and 1 button + 1 CDS Entity with 2 fields and tried to move that around. Same error on all variations.
Could someone please kindly follow up on that issue? I could provide logfile if necessary.
I really depend on that functionality.
Many Thanks
BR
Martin
