You are a solution architect on a brownfield project where an SAP ECC 6.0 system is being migrated to SAP S/4HANA Cloud public edition. Two mission- critical legacy applications must be migrated to the new system. There is some debate on the project team as to the appropriate programming model to use:

•Application 1 was originally written using classic ABAP. The underlying SAP tables that the application originally relied on have been removed and the data now exists in a new simplified table in SAP S/4HANA Cloud public edition (to which table extensions are not permitted). Additional data needed for the application resides in SAP Ariba. Remote interfaces exist for both to select the data.

•Application 2 was originally written using Java and relied upon tables from the SAP ECC 6.0 system as well as SAP PLM 4.0. The PLM system will be retired; however, the SAP S/4HANA Cloud public edition instance has all the data needed for the application. No remote interfaces exist to select the data.
