ABAP Core Tools for Visual Studio 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

   

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
2. Open the Command Palette or Ctrl+Shift+P.
3. Type ABAP: Log On to Destination

   

4. Select the Destination. This will prompt to open the system in browser to enter the logon credentials

   

1. Open the Command Palette or Ctrl+Shift+P.
2. Type ABAP: Open Object

   

3. Give the name of the object. E.g “I_Currency”. You can search for class, data definition.

   

4. You can analyse the opened object.

   

5. Objects with unsaved backend changes are marked (L) — they must be activated (Ctrl+F3) to become active in the system.

1. Open the Command Palette or Ctrl+Shift+P.

2. Type ABAP: Create New ABAP Object

   

3. You can choose the object type that you want to create. Choose ‘Database Table’.

   

4. Choose the package name that was used in the previous step.

   

5. Enter the name of the Database Table ‘ZADT_Travel_###’to be created and press Enter to confirm.

   

6. Give a Description

   

7. A new ‘Database Table’ will be created.

8. Copy the below code and replace it in the Database table. Replace ‘###’ with the unique number that you have given.

1. Open the Command Palette or Ctrl+Shift+P.

2. Type ABAP: Check Object. This will run the syntax check on the opened object. The message ‘Running Syntax check’ appears in the Status bar

   

3. To Activate an object: open the Command Palette Ctrl+Shift+P and Type ABAP: Activate.

   

   You can also use Ctrl+F3. Activate icon is also available on top of the editor window.

   

1. Open the Command Palette or Ctrl+Shift+P.

2. Type ABAP: Create New ABAP Object

   

3. You can choose the object type that you want to create. Choose ‘Class’.

   

4. Choose the package name that was used in the previous step.

   

5. Enter the name of the Class to be created and press Enter to confirm.

   

6. Give a Description

   

7. Choose a Super Class and interface if required.

   

8. A new ‘Class’ will be created.
