Projection CDS provider contract

[alikhach]

Hello,

I've created projection abap CDS and see warning message: Transactional Provider Contract expected for Projection View XXXX.

Eclipse offers to add a solution from 3 options:

• provider contract transactional_query
• provider contract transactional_projected_entity
• provider contract transactional_extensibility_projection

I've added first and warning disappeared. It is ok.

But I can't find what all this options mean? What is provider contract? And why i have to add it?

BR,

Alex

I do not get the options to add the contract. For me, the transactional applications in the managed scenario are not created.

Will investigate if there is a relation to this and post back. But, I too could not understand what is a Provider Contract in the first place.

I am also facing this error. Following the Thread

Hi Alex,

the addition provider contract is used for defining an intended runtime for your CDS Projection View. Today, most of the CDS Projection Views are used in the context of transactional RAP applications. By that, feature restrictions are applied, to guarantee the successful execution in the transactional runtime.

As there are different runtimes with different capabilities, the data model of an application needs to be prepared for such a runtime. So if you want to create a CDS Projection View for a transactional RAP application in order to create a specific view on your business object, please use the addition provider contract transactional_query.

Further provider contracts will be supported in the near future, to give access to more features in different runtimes.

Best regards
