Which method calls in a RAP validation create translatable messages?

The correct choice involves the use of a translatable text format that allows the message to be easy to localize. By using the syntax with parentheses, the method enables the text string to refer to a language-specific message that is maintained in a translation table.

In the selected option, the syntax 'Airport does not exist'(ane) indicates that the message should be translated according to the language settings in the SAP system. The 'ane' specifies the key used to look up the appropriate translation for the message in the current language context. This capability is essential for applications that will be used in environments where multiple languages are necessary, ensuring that users experience the application in their preferred language.

This design promotes usability and accessibility, making it particularly important in diverse environments. Translatable messages enhance user experience by providing feedback in the user's native language, thereby reducing misunderstandings and errors during application use.

In contrast, choices that do not utilize the translation key or focus solely on static strings do not support localization, limiting the adaptability of the application for users from different linguistic backgrounds. Therefore, the selected approach stands out for its localization capabilities, making it the correct choice for generating translatable messages in SAP RAP validations.
