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 INNER JOIN DTAB_EMP_BILL AS empbill

                       ON empinfo.pernr = empbill.pernr

                    WHERE empbill.mandt = empinfo.mandt

                    GROUP BY 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:
