To consume a HANA procedure in ABAP, you can follow the below steps:
Create a HANA procedure in your HANA system using the SAP HANA studio or SAP HANA Web-Based Development Workbench.
In your ABAP system, create a database procedure proxy object. You can do this by using the transaction code SE37 or SE80.
In the database procedure proxy object, you will need to create an import parameter, an export parameter, and a table parameter that will be used to exchange data between ABAP and HANA.
In the source code of the database procedure proxy object, you will need to define a connection to the HANA system using the appropriate connection parameters.
Next, you will need to call the HANA procedure in your ABAP program by using the CALL PROCEDURE statement, passing the input parameters and receiving the output parameters.
After the HANA procedure is executed, the output data can be processed and used in the ABAP program as needed.
Finally, you can test the integration between ABAP and HANA by executing the ABAP program.
In summary, the steps involve creating a database procedure proxy object in ABAP and then calling the HANA procedure from the ABAP program using the appropriate input and output parameters.
