Using Translatable Text in ABAP

Copy the template class. If you finished the previous exercise, you can skip this task and continue editing your class ZCL_##_SOLUTION.

1. Copy class /LRN/CL_S4D401_TCS_TIMESTAMP to a class in your own package (suggested name: ZCL_##_SOLUTION, where ## stands for your group number).

   1. In the Project Explorer view, right-click class /LRN/CL_S4D401_TCS_TIMESTAMP to open the context menu.

   2. From the context menu, choose Duplicate ....

   3. Enter the name of your package in the Package field. In the Name field, enter the name ZCL_##_SOLUTION, where ## stands for your group number.

   4. Adjust the description and choose Next.

   5. Confirm the transport request and choose Finish.

2. Activate the copy.

   1. Press Ctrl + F3 to activate the class.

Make sure you are logged on with the original language of your global class. Then adjust the implementation of method GET_OUTPUT of local class LCL_CARRIER. Replace the literal text in string templates with translatable text from the text pool.

1. Display the original language of your ABAP class and make sure you are logged on in the same language.

   1. Open the source code of your global class ZCL_##_SOLUTION.

   2. From the tabs below the editor choose the Properties tab.

   3. Take note of the Original Language property. It should be set to EN.

   4. In the Project Explorer view, analyze the description of your ABAP cloud project. After the system ID, the logon client, and the user ID, it displays the logon language.

   5. If the logon language does not match the original language of your ABAP class, create a new project with the correct logon language.

2. Navigate to the implementation of method GET_OUTPUT in local class LCL_CARRIER.

   1. For example, you can open the Local Types tab in the editor and search for METHOD get_output.

   2. Alternatively, you can expand ZCL_##_SOLUTION → LCL_CARRIER in the Outline view on the left and choose GET_OUTPUT.

3. Adjust the string template in the first APPEND statement. Replace the literal text with an embedded text literal.

   Hint

   Keep in mind that the curly brackets for embedded expressions require blank spaces on the inside.

   1. Adjust the code as follows:

      Code Snippet

      Copy code

      Copy code

      Switch to dark mode

      Switch to dark mode

      123
      
         APPEND |Carrier Name: { me->name } | TO r_result.
      

4. Link the text literal to a text symbol (suggested ID for the text symbol: 001).

   Hint

   Keep in mind that no blanks are allowed inside the brackets or between the closing quote and the opening bracket.

   1. Adjust the code as follows:

      Code Snippet

      Copy code

      Copy code

      Switch to dark mode

      Switch to dark mode

      123
      
         APPEND |{ 'Carrier Name:' } { me->name } | TO r_result.
      

5. Repeat this for the literal text in the other string templates. (Suggested IDs for the text symbols: 002, 003, 004).

   1. Adjust the code as follows:

      Code Snippet

      Copy code

      Copy code

      Switch to dark mode

      Switch to dark mode

      123456
      
          APPEND |{ 'Carrier Name:'(001)       } { me->name } | TO r_result.
          APPEND |{ 'Passenger Flights:'(002)  } { lines( passenger_flights ) } | TO r_result.
          APPEND |{ 'Average free seats:'(003) } { get_average_free_seats(  ) } | TO r_result.
          APPEND |{ 'Cargo Flights:'(004)      } { lines( cargo_flights     ) } | TO r_result.
      

6. Use a quick fix to create the first text in the text pool with a maximum length of 20.

   1. Place the cursor on (001) and press Ctrl + 1.

   2. Choose Create text 001 in text pool.

   3. Choose the slider to set the Maximum Length to 20 and choose Finish.

7. Repeat this to create the other texts in the text pool. Use the same maximum length.

   1. Perform step as before.

8. Analyze and activate the text pool.

   1. Hold down the Ctrl key and choose any of the text IDs to navigate to the text pool.

   2. The source code of the text pool should look like this:

      Code Snippet

      Copy code

      Copy code

      Switch to dark mode

      Switch to dark mode

      12345678910111213
      
      @MaxLength:20
      001=Carrier Name:
      
      @MaxLength:20
      002=Passenger Flights:
      
      @MaxLength:20
      003=Average free seats:
      
      @MaxLength:20
      004=Cargo Flights:
      

   3. While in the text pool press Ctrl + F3.

9. Activate and test the global class as a console app.

   Note

   You should not see any difference. The improvement is, that the texts are translatable now. But this has no effect until the system administrator actually creates a translation project. But this is beyond the scope of this course.

   1. Return to the implementation of method GET_OUTPUT.

   2. Press Ctrl + F3.

   3. Press F9.
