Is there any official SAP Documentation about RAP Facades?

[DiegoValdivia]

Hi,

· While reading document “Extend SAP S/4HANA in the cloud and on premise with ABAP based extensions”( https://www.sap.com/documents/2022/10/52e0cd9b-497e-0010-bca6-c68f7e60039b.html), I saw that, on page 21, it’s mentioned that we developers must substitute BAPIs with RAP Facades.

Based on this, could you confirm if there’s some official SAP document about RAP Facades? I mean, some document where SAP explains their function and most of all, how to use them in the real world to substitute BAPIs.

I've gone through the most recent posts about RESTful Application Programming Model, as well as posts about Embedded Steampunk, but haven't found any detailed documentation about RAP Facades.

Thanks.

Hello Diego,

Released SAP RAP BO Interfaces are referred to as RAP Façades. Similar to the facade of a building, they represent the exterior of the given application. Released RAP BO Interfaces provide stable local API-based access to the RAP-based SAP applications.

For more information, see Business Object Interface Consumption in the RAP Development Guide: https://help.sap.com/docs/btp/sap-abap-restful-application-programming-model/business-object-interfa...

Kind regards,

Hi Owen,

Thank you for your answer.

I've just reviewed the post, unfortunately it doesn't provide any information about RAP Facades.

I viewed the TechEd video "Extend SAP S/4HANA on Stack with the ABAP RESTful Application Programming Model (RAP)". It shows some small example about using a RAP Facade to create a Sales Order, but it doesn't go any further.

I'm looking for some documentation where SAP explains for example: Which BAPIs where replaced by RAP Facades? Does RAP Facades perform the same validations as BAPIs? Do they return error messages for inconsistent data same as BAPIs? Does RAP Facades can be enhanced to include custom logic same as we do with BAPIs + BADis? I mean, there are a lot of implications.
