You want to change the translated text of SAP Fiori launchpad tiles, catalogs, or group titles in the configuration layer. This is possible using the standard SAP translation tools.
To find the text in the translation system and correct it, translators require the text ID and the configuration ID. To retrieve these IDs, you use Fiori Launchpad Checks (transaction /UI2/FLC).
To translate the texts, you access the standard SAP translation environment. The translation follows the standard ABAP translation process. This is the same process as for translating Web Dynpro component configurations.
