E2E – Consuming HANA procedures using ADBC

Author:          Sathish Kumar Dharmaraj

Company:      NTT DATA Global Delivery Services Private Limited


Our certain section of ABAP reports being executed in SAP NW 7.3 on Oracle DB and by running these reports for large selection takes lot of time in execution and it occupies lot of resources. Hence, on having HANA DB, push down the entire logic to HANA by replicating the source tables using SLT, developing the procedures on base tables and consuming the procedures in SAP using ADBC.

This end to end guide illustrates the replication method of SLT, building the procedures and how to consume in SAP.


1) Go to Programs -> SAP HANA -> SAP HANA Studio

15) Table will be initially in Load (Action) – Scheduled (Status) and when the load is in progress it shows the Action as Load and Status as In Process, when the load is completed, it shows the action as Load and Status as Executed. For the replication, it shows the action as Replicate and Status as In Process. You can monitor the status by clicking the refresh button in the top right corner of the below screen.

23) Select your package -> Right Click -> New -> Procedure

Pic 23.jpg

24) Provide procedure details and choose the default schema were the tables being replicated via SLT.

26) Procedure has different panes, Script View, Input Pane and Output Pane.

a) Create the output parameters from the Output pane, Select Output Parameters -> Right Click -> New (List out the fields for output)

b) Save and Activate the procedure

27) Once the procedure been activated, it will be stored under _SYS_BIC schema -> Procedure

Pic 28.jpg

28) Execute the procedure using CALL statement

Pic 29.jpg

29) Result will be shown as below

30) To insert the data into an table, use CALL procedure WITH OVERVIEW

Follow below instructions for calling procedures in ABAP

35) Declare types which is exact similar to Output Parameter structure

36) SQL connection data declaration and its variables

37) Fetching the DB connection name should be maintained in DBCON table or using DBCO transaction.

Pic 34.jpg

38) Fetch the table name using the below CALL procedure WITH OVERVIEW

Pic 36.jpg

39) Execute Query which will return the table name

40) Execute the table using select and fetch the data

41) Assign the table result into target variable/internal table.

I hope this document helps to give an idea to extract the information from HANA using ADBC connection.
