Creating Database Procedure Proxies

To access the HANA-based application logic in ABAP, you have to create the corresponding ABAP repository objects that are already implemented at database level as HANA database procedures.

1. In your ABAP project, select the relevant package node in the Project Explorer.
2. Open the context menu and choose  New  Other ABAP Repository Object  Dictionary  Database Procedure Proxy  to launch the proxy creation wizard.
3. In addition to the Project and Package, enter the Name and Description for the proxy to be created.
4. Enter the name of the appropriate HANA database procedure that has already been created in the ABAP system in question. Then choose Next.
   Tip When editing the name of the HANA Procedure, you can benefit from the content assistant functionality by pressing Ctrl + Space in the corresponding field. Note that entire name of the database procedure comprises the HANA package name (first part) and the actual procedure name.
   Note The wizard automatically proposes a name IF_<PROXY_NAME> for the ABAP interface to be created. This interface contains the ABAP data type definitions. However, you can change the proposal in keeping with your own naming conventions for ABAP object types.

   Note The ABAP Development Tools support the recommendation that only one proxy should be created for each single HANA database procedure: Every time you want to create more than one proxy for a single HANA database procedure, you will be faced with a corresponding warning message in the creation wizard.
