Consume HANA artifacts using ABAP- External View

Abhishek Agrawal

Step 1: In HANA studios go to ‘SAP HANA Development’ or ‘Modeler’ prospective.

Step 2: Open ‘Content’ folder and create a new package (if you do not have a

package).

Step 3: Right click on above created package and under ‘New’ select ‘Attribute

View’ (or any other depends on your requirement.)

Step 4: Give name and description of your view and click on finish.

Step 5: Select tables from ‘Catalog’ folder and drag n drop it to ‘Data Foundation’.

Step 6: Create join links between table fields and add output fields and calculated

fields as per requirement.

Step 7: Save and Activate the view and check the data by using ‘Data Preview’

option.

At this point we are done with our HANA view, now we need to create External

View corresponding to this HANA view.

Steps to create external view:

Step 1: Go to ‘ABAP’ prospective.

Step 2: Right click on ABAP package under which you want to create this external

view. Under ‘New’ click on ‘Other ABAP Repository Object’

Step 3: Expand ‘Dictionary’ folder and click on ‘Dictionary View’.

Step 4: Enter name and description of view and select ‘External View’ radio

button and browse and select your HANA view.

Step 5: Click on Next, Finish and then activate the view, this will create your

external view in you ABAP system, you can cross check in SE11.

Note: In case if you make any changes to your HANA view then you need to come

to your external view and synchronize if by using ‘Synchronize’ button(check in

above screen shot).

At this point of time we have our External View ready that is pointing to HANA

View.

Steps to consume external View:

External view is just like any table in your ABAP system (like MARA) and you

can fetch data from it just like any other table.

Code snippet to get data from external view.

REPORT ztest_oia_t049_open_days_ex_v.

TYPES: BEGIN OF ty_bp_order,

bp_id TYPE snwd_bpa-bp_id,

open_days TYPE int4,

END OF ty_bp_order.

DATA: lt_bp_order TYPE TABLE OF ty_bp_order.

SELECT bp_id SUM( open_days )

INTO TABLE lt_bp_order

FROM zoia_opn_days_ex

GROUP BY bp_id.

SORT lt_bp_order BY bp_id.

LOOP AT lt_bp_order ASSIGNING FIELD-SYMBOL(<fs>).

WRITE: / 'Order placed by BP' ,<fs>-bp_id.

WRITE: '=', <fs>-open_days, /.

ENDLOOP.
