Unable to create a C1 release contract on CDS Table Function

[martinc_mb38]

(UPDATE - see below)

To access certain data, we have implemented a CDS Table Function in a Standard ABAP/Tier 2 package, which we would then need to be consumed by a Tier 1/Cloud for ABAP CDS View.

(We are following the recommendation here: Creating Tier 2 Cloud APIs).

However, in ADT the options to add a C1 or C2 release contract are greyed out / unavailable for the CDS Table Function:

Also, when trying to add a C0 release contract, it gives this message: "C0 release is not supported for entity type F.":

Trying to consume the CDS Table Function in a Tier 1 CDS View is impossible, and also results in an error (presumably until we can add a C1 release contract).

UPDATE 23.04.2025:

We created a case for this issue with SAP, referencing the above documentation. SAP came back with the following reply:

Dear customer,

As Creating Tier 2 Cloud APIs says:

Currently, the object types recommended by SAP to be wrapped are as follows:

• ABAP RESTful application programming model BO
• Function Module
• Class / Interface
• CDS View
• Table

Currently SAP does not support adding release contracts to CDS Table Functions which means they cannot be exposed as public APIs or consumed by Tier 1 CDS Views directly

We pointed out to them that the documentation in fact goes on to say:

For mitigation scenarios, SAP recommends the following:

• CDS Table Function
• AMDP Method

For the first option, a CDS view (which accesses the table function) would serve as the released object for tier 1 usage and for the latter option, a class (accessing the method) would suffice.

What could potentially happen now, is that SAP changes the documentation to cover such a shortcoming. I hope not, because one of our project requirements depends on being able to use this functionality.

I've made a screenshot of the current doc:
