# ABAP Basic Features for Visual Studio Code
You will explore the ABAP Development Tool (ADT) functionality in Visual Studio Code which do not require Agentic AI capabilities.
## Introduction
ABAP development tools for Visual Studio Code provides an efficient and feature-rich set of tools for ABAP development within the ABAP Cloud development model. It brings modern ABAP development to your editor, enabling you to create, edit, debug, and manage ABAP artifacts directly in VS Code. You need to set up your development environment in **Visual Studio Code** and connect it to your ABAP system.
This tutorial focus on non-Agentic AI capabilities and do not need any coding agent extension in Visual Studio Code (for e.g: GitHub Copilot)
## Prerequisites
You have connected an ABAP system to Visual Studio Code following the previous tutorial in this group .
## You will learn
- How to explore and adjust the generated artifacts (CDS views, behavior definitions, metadata extensions) directly in Visual Studio Code
- How to publish the service binding and preview the SAP Fiori elements app in the browser
- How to run ABAP unit tests from Visual Studio Code
- How to debug the SAP Fiori App from Visual Studio Code
### Add package as folder to workspace in VS Code
You need to have a package created in ADT. This package can be added as a folder to workspace.
1. Open the **Command Palette** or **`Ctrl+Shift+P`**.
2. Type `ABAP: Add Package as folder to Workspace`
3. Search the package you have created in ADT.
4. Enter Workspace folder name.
5. Folder is added to Workspace
### Logon to Destination
During any time if you have been logged out of system, you need to Log On to the Destination to continue the work by following options:
1. Right click on the Package which is added as a Folder to Workspace and choose "Log On to Destination"
OR
1. Open the **Command Palette** or **`Ctrl+Shift+P`**.

6. Give a Description
7. In the next step you can choose the reference object for the new CDS view to be build
8. A new 'Data Definition' will be created.
9. Copy the below code and replace it in the CDS View Entity. Replace '###' with the unique number that you have given.
```CDS
@AbapCatalog.viewEnhancementCategory: [#NONE]
@AccessControl.authorizationCheck: #NOT_REQUIRED
@EndUserText.label: 'CDS view for ADT Tools'
@Metadata.ignorePropagatedAnnotations: true
define view entity ZI_ADT_Travel_### as select from ZADT_TRAVEL_###
{
key travel_id as TravelId,
agency_id as AgencyId,
customer_id as CustomerId,
begin_date as BeginDate,
end_date as EndDate,
@semantics.amount.currencyCode: 'CurrencyCode'
booking_fee as BookingFee,
@semantics.amount.currencyCode: 'CurrencyCode'
total_price as TotalPrice,
currency_code as CurrencyCode,
description as Description,
overall_status as OverallStatus,
created_by as CreatedBy,
created_at as CreatedAt,
local_last_changed_by as LocalLastChangedBy,
local_last_changed_at as LocalLastChangedAt,
last_changed_at as LastChangedAt
}
```
10. Activate the new CDS View Entity by following Step 5
### Open with ADT for Eclipse
We will open the newly created CDS view in ADT for Eclipse.
1. Open the **Command Palette** or **`Ctrl+Shift+P`**.
2. Type `ABAP: Open with ADT for Eclipse`
3. CDS View Entity is opened in ADT for Eclipse.
### Preview of a Fiori Application
1. Open the **Command Palette** or **`Ctrl+Shift+P`**.
2. Type `ABAP: Open Object`
3. Search for the Service Binding '/DMO/UI_TRAVEL_APPR_M_O2'
4. Object opens and there are 3 options.
- Publish/Unpublish depending if the Service binding is Published or not
- Preview: To preview the Fiori Application
- Create a SAP Fiori app
5. Click on Preview
6. This will launch Fiori Application in Preview mode.
### Create a new class method to display 10 records
1. First create a new class **`ZCL_ADTVSCODE_###`** by following the same steps in **Create a data generator Class** section until Step 4. In the newly created class we will add a new method to display 10 rows from the table **`/dmo/carrier`**. Copy the below code and replace it with the code in the new class.
```ABAP
CLASS zcl_adtvscode_### DEFINITION
PUBLIC
FINAL
CREATE PUBLIC .
PUBLIC SECTION.
INTERFACES if_oo_adt_classrun.
PROTECTED SECTION.
PRIVATE SECTION.
TYPES tt_carriers TYPE STANDARD TABLE OF /dmo/carrier WITH DEFAULT KEY.
METHODS get_carriers RETURNING VALUE(rt_carriers) TYPE tt_carriers.
ENDCLASS.
CLASS zcl_adtvscode_### IMPLEMENTATION.
METHOD if_oo_adt_classrun~main.
out->write( get_carriers( ) ).
ENDMETHOD.
METHOD get_carriers.
SELECT * FROM /dmo/carrier INTO TABLE @rt_carriers UP TO 10 ROWS.
ENDMETHOD.
ENDCLASS.
```
2. To view the result in the console, Open the Output from View option.
3. Run the class to see the output. Open the **Command Palette** **`Ctrl+Shift+P`**.
4. Type `ABAP: Run ABAP Application(Console)`
5. You can see the result under Output tab.
### Debug a method
1. To debug let us use a the same class created in the previous step. First put a Breakpoint at the `SELECT` statement by clicking to the left of the line number as shown in the below screenshot.
2. Once the breakpoint is set, it'll be highlighted.
3. To Run the ABAP Application, you can right click on the editor and choose Run ABAP Application (Console).
4. Run and Debug view will be opened to the left of the editor. You will see the parameter `RT_CARRIERS` which doesnt have any entries now.
5. Now let us execute the select statement by clicking on **`Step Into`** or **`F11`**.
6. After executing the select statement we can see that `RT_CARRIERS` now has 10 entries.
We can open each record to analyze the data.
### Run ABAP Test Cockpit (ATC) Checks.
Using ATC you can detect the quality issues with regards to performance, security & programming conventions by regularly executing static and dynamic checks. We will run ATC Checks on the same class used to Debug in the above step.
1. Open the **Command Palette** **`Ctrl+Shift+P`**.
2. Type `ABAP: Run ABAP Test Cockpit` or **`Ctrl+Shift+F10`**
3. Check the `Problems` tab to view the ATC findings as shown below.
### Run Unit Test
1. Enhance the CDS view **`ZI_ADT_Travel_###`** created in Step 7 to include a new **`DiscountedFlightPrice`** field.
Add the following code lines for the field **`DiscountedFlightPrice`** to provide **10%** discount on the total price if **`total_price is > 1000`**.
```ABAP
case
when total_price > 1000 then cast(total_price as abap.dec(16,2)) * cast('0.90' as abap.dec(5,2))
else cast(total_price as abap.dec(16,2))
end as DiscountedFlightPrice,
```
2. Your CDS data definition  **`ZI_ADT_Travel_###`** should look like this:
```CDS
@AbapCatalog.viewEnhancementCategory: [#NONE]
@AccessControl.authorizationCheck: #NOT_REQUIRED
@EndUserText.label: 'CDS view for ADT Tools'
@Metadata.ignorePropagatedAnnotations: true
define view entity ZI_ADT_Travel_###
as select from zadt_travel_###
{
key travel_id as TravelId,
agency_id as AgencyId,
customer_id as CustomerId,
begin_date as BeginDate,
end_date as EndDate,
@Semantics.amount.currencyCode: 'CurrencyCode'
booking_fee as BookingFee,
@Semantics.amount.currencyCode: 'CurrencyCode'
total_price as TotalPrice,
case
when total_price > 1000 then cast(total_price as abap.dec(16,2)) * cast('0.90' as abap.dec(5,2))
else cast(total_price as abap.dec(16,2))
end as DiscountedFlightPrice,
currency_code as CurrencyCode,
description as Description,
overall_status as OverallStatus,
created_by as CreatedBy,
created_at as CreatedAt,
local_last_changed_by as LocalLastChangedBy,
local_last_changed_at as LocalLastChangedAt,
last_changed_at as LastChangedAt
}
```
3. Save  **Ctrl+S** and activate  the changes.
4. Now switch to Eclipse and create a unit test class for the CDS view above.
In the **Project Explorer**, right-click on the CDS data definition **`ZI_ADT_Travel_###`** and select **New ABAP Test Class** from the context menu.
5. Enter the information below in the popup for the new ABAP Class that will be created and click on **Next**.
- Name: **`ZCL_TEST_CDS_TRAVEL_###`**
- Description: ***`Test Class for CDS View ZI_ADT_Travel_###`***
6. The popup now displays the SQL dependencies for the CDS Test Double Framework.
7. Click on **Next** 2 times and finally click on **Finish**.
8. Copy and replace the entire code inside the test class with the code below:
