Create a program to translate text

In the SAP system, create an executable program in your custom namespace (for example, Z or Y) by using transaction SE38 .

In the SAP GUI, enter transaction code SE38 .
In the Programfield, enter a name of your program, for example, ZDEMO_TRANSLATE .
Click Create.
Specify the program attributes:
1. In the Titlefield, enter a title of your program, for example, Translate from English to German .

Replace DEMO_TRANSLATE with the client key name.

Run your application in SE38 . If successful, the following output displays:

'Translation Successful'
'Translated Text is: Die Erde ist der dritte Planet von der Sonne'
