Language ​

abap2UI5 picks the user's logon language automatically from the SAP session — every translated text retrieved via z2ui5_cl_util=>trans_get_text( ), every OData/CDS label, every message class is returned in that language. For most applications no extra configuration is required.

Override the Backend Language ​

To force a specific SAP logon language at startup, append the sap-language URL parameter:

…/z2ui5/sample?sap-language=EN
…/z2ui5/sample?sap-language=DE

The value is a one- or two-character SAP language key (typically ISO 639-1, e.g. EN, DE, FR, JA). The server sets the user's session language for this request, so backend reads, OData calls and translated texts all use that locale.

Override the UI5 Frontend Locale ​

The UI5 framework keeps a separate locale for date and number formatting, control labels ("Search", "Cancel", …) and the calendar week. By default UI5 derives it from the browser. You can pin it with the URL parameter sap-ui-language:

…/z2ui5/sample?sap-ui-language=de

Most apps don't need this — the browser locale and the SAP logon language agree in practice. Set it explicitly when you need full control, e.g. in test environments.

Forcing the Frontend Locale at Startup ​

You can also pin the UI5 locale via the bootstrap, instead of relying on a URL parameter:

abap
METHOD z2ui5_if_exit~set_config_http_get.

    cs_config-t_add_config = VALUE #(
      ( n = `data-sap-ui-language` v = `en` ) ).

ENDMETHOD.

See Bootstrap Attributes for more on this mechanism.
