T6. Consuming HANA artifact Stored Procedure using ABAP Proxy Procedure.
Steps to create Stored Procedure:
Step 1: Go to ‘Modeler’ or ‘SAP HANA Development ‘prospective and right click on your package and create a new procedure.
Step 2: Enter name and description, select the ‘Default Schema’ (SAP-SID) and Run With as ‘Invoker’s Right’ and click on finish.
Step 3: Add ‘Output’ and ‘Input’ parameters by right clicking on the respective folders
Step 4: Place the code in the procedure editor
BEGIN
et_last_rev_bill = SELECT empinfo.pernr as PERNR, DAYS_BETWEEN(empbill.BILL_DATE,CURRENT_UTCDATE) AS LAST_REV_BILL
FROM DTAB_EMP_INFO AS empinfo INNERJOIN DTAB_EMP_BILL AS empbill
ON empinfo.pernr = empbill.pernr
WHERE empbill.mandt = empinfo.mandt
GROUPBY empinfo.pernr, empbill.bill_date ;
END;
/********* End Procedure Script ************/
Step5: Save and activate the procedure. Execute the procedure in ‘SQL Console’.
Call"_SYS_BIC"."mohas97_ha5/ZEMP_BILL_PP"(?) WITH OVERVIEW;
Call"_SYS_BIC"."mohas97_ha5/ZEMP_BILL_PP"(?);
Now create a Proxy Procedure in ABAP:
Step 1: Go to ‘ABAP’ prospective.
Step 2: Right click on ABAP package under which you want to create this Proxy Procedure. Under ‘New’ click on ‘Other ABAP Repository Object’
Step 3: Choose ‘Database Procedure Proxy’.
Step 4: Enter name, description, HANA s procedure name 
Step 5: Now your proxy procedure is created just activate the object.
Source code to Consume the ‘Proxy Procedure’ in ABAP:
DATA: lt_bill_rev_days TYPE TABLE OF if_emp_bill_proxy_procedure=>et_last_rev_bill,
lv_count TYPE i.
CALL DATABASE PROCEDURE emp_bill_proxy_procedure
IMPORTING et_last_rev_bill = lt_bill_rev_days.
LOOP AT lt_bill_rev_days ASSIGNING FIELD-SYMBOL(<fs_bill_rev_days>).
WRITE: / 'Days Since Bill Rate is changed' ,<fs_bill_rev_days>-pernr.
WRITE: '=', <fs_bill_rev_days>-last_rev_bill , /.
ENDLOOP.
Output:
