How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (2023)

hello everyone,

focusing on beginners, I am writing this blog to explain about how to create OData service and consume OData service to UI5 application (through VSCode) and to work on CURD operations from UI5 Application to backend ABAP HANA Server (On Premises) in detail.

Info: – Here I am using SAP GUI 7.50 Version. if you are

running with older version please download and install with SAP GUI 7.50 Version for better understand this blog.

Let’s begin from OData service creation

Note:

Please do follow the number orders and square boxes as mentioned in images as RedColor.

Before start be ready with database table otherwise create it in SE11 – Tcode

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (1)

Database Table

This is the database table which I have created and will perform CRUD Operation from the UI5 Application.

Step 1:

Go to SEGW – Tcode and click on Create project and provide valid Project name and description and click on Local object it will create new project.

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (2)

now Expand the project and right click on Data Model project nav to import then click on DDIC Structure

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (3)

Now provide proper name as Entity Type Name and import the database table by name of table as you created earlier and click on next

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (4)

Select check box for the field selection on entity and click on next

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (5)

Now make any field as primary key it can be one or more but mandatorily and click on Finish

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (6)

Now your database table will be assigned to OData project successfully. But you can’t access all fields from the database table for the you need to redefine the methods.

Click on generate runtime objects and it will retain all your defaults methods to your OData project.

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (7)

Now double click on ZCL_YOUR_PROJECT_NAME_DPX_EXT(left side) and double click on ZCL_YOUR_PROJECT_NAME_DPX_EXT from Runtime artifacts section to redefine all your methods.

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (8)

Now you will see the screen of all your classes methods and go to Method section click on inherited Methods and nav to YOURENTITYNAME_GET_ENTITYSET Method, right click on it nav to Redefine option and it will open window to write your logic(clear the commented code and write code as given the following code and respective Methods).

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (9)

Make sure it should be in change mode and after implementing new logic for GET_ENTITYSET method. Save (Ctrl+S) it and Activate (Ctrl+F3)

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (10)

Now repeat the same steps for following methods. for GET_ENTITY, CREATE_ENTITY,DELETE_ENTITY and UPDATE_ENTITY,

GET_ENTITY (for reading single record from table)

* Fetch Single record based on the key in the URI DATA : wa_key TYPE /IWBEP/s_MGW_NAME_VALUE_PAIR.* Read the Key from URI READ TABLE IT_KEY_TAB INTO wa_key WITH KEY name = 'Id'. IF sy-subrc EQ 0. SELECT SINGLE * FROM zmd_user_table INTO CORRESPONDING FIELDS OF er_entity WHERE Id EQ wa_key-value. ENDIF.

CREATE_ENTITY (for creating new record)

* Create a record DATA : wa_osuerdata TYPE zcl_zmd_odatacrud_mpc=>ts_zuserdata.* Read the data from Request body io_data_provider->read_entry_data( IMPORTING es_data = wa_osuerdata ). MOVE-CORRESPONDING wa_osuerdata TO er_entity. MODIFY zmd_user_table FROM wa_osuerdata.

UPDATE_ENTITY (to update particular record)

DATA : ls1 TYPE ZCL_ZMD_ODATACRUD_MPC=>ts_zuserdata.io_data_provider->read_entry_data( IMPORTING es_data = ls1).* CATCH /iwbep/cx_mgw_tech_exception. "UPDATE zmd_user_table FROM ls1.

DELETE_ENTITY (to delete the record)

DATA : LS2 TYPE /IWBEP/S_MGW_NAME_VALUE_PAIR. "READING TABLE " READ TABLE IT_KEY_TAB INTO LS2 WITH KEY name = 'Id'. "DELETING THE RECORD " DELETE FROM zmd_user_table WHERE Id = LS2-VALUE.

Save and Activate, Now come back to SEGW home screen by clicking back button and Click on generate runtime objects andnav to Service Maintenance and double click on it and Register Service till then Registration Status will be known.

now the Registration Status will be updated, now click on SAP Gateway Client (if any warnings popup means just click on Yes ) it will navigating to Gateway Client.

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (13)

here select the EntitySet that your created and click on Execute it will fetch all records from the table.

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (14)

Now you will see the all the records that your created for the table. And returns the HTTP Status code 200 if the GET_ENTITYSET methods logic was properly. Otherwise, Status code will be 401.

Step 2: OData CRUD Operations from UI5 application to SAP S/4 HANA Server (onPremise)

How to Create OData Service and CRUD Operations from UI5 Application to ABAP HANA Server (OnPremises) (16)

this is my OData from the backend which I have created (refer the Database table image from the beginning) and consumed it in my UI5 application.

Conclusion

In order to do normal CRUD operations should access records by ID. As I am modifying particular records by database table ID. By this I can change only single record with multiple fields for same in one sing HTTP request. Not multiple records.

Hope I find it will we be helpful. If any queries please welcome on comment sections.
