Duty to cooperate

The deeper SAP customers delve into the secrets and structures of the Business Technology Platform, the more they realize that they are dealing with the old HEC, Hana Enterprise Cloud. Label fraud? Perhaps. The fact is that many existing SAP customers can hardly tell the difference between BTP and HEC.
Perhaps BTP really can do more than HEC, but from the perspective of SAP Basis, from the perspective of a CCoE manager, the difference is marginal - but not for the CFO and CIO! The favorable fees of SAP's Business Technology Platform are only explained after several months of operation.
There is a kind of duty to cooperate in the SAP cloud. What the outsourcer or hoster used to provide as a service for the existing SAP customer must in many cases be performed independently by the existing SAP customer in the SAP cloud. Naturally, SAP also offers services here, but these usually have to be paid for separately. If the SAP inventory customer cannot fulfill his obligation to cooperate, it will be expensive!
However, a full cost calculation is difficult to obtain because experience with SAP's cloud computing is lacking. The Business Technology Platform thus remains an expensive one-way street, because the cloud exit strategy back to the less expensive on-prem system is missing.
