Lack of Financial Bias Notice: The vast majority of content available on the Internet about SAP is marketing fiddle-faddle published by SAP, SAP partners, or media entities paid by SAP to run their marketing on the media website. Each one of these entities tries to hide its financial bias from readers. The article below is very different.

  • First, it is published by a research entity.
  • Second, no one paid for this article to be written, and it is not pretending to inform you while being rigged to sell you software or consulting services. Unlike nearly every other article you will find from Google on this topic, it has had no input from any company's marketing or sales department.

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.
