Our Analysis
- The OData interface is both problematic and not as flexible as SQL.
- SAP should not be defining how you consume or view the data. SAP offers CDSs. Customers can use them or not use them depending upon whether they find they fit their needs.
- Business logic cannot be published to the CDSs.
Conclusion
SAP has this way of presenting their options as if they are natural law. If the CDSs are good, a test will show this when compared to your alternative. The things that SAP is saying on this topic are adding up. We record false statements that are routinely made to customers. The idea inside of SAP is that customers have no real right to any truth. Anything is said that supports whatever SAP wants the customer to do.
