Hi, I not absolutely sure about your question and the target you have.
I guess you want to build a multi-language application?
If this is the case you need to differentiate 3 things:
a) language of Qlik Sense Client
b) language of field names
c) language of data
Regarding a) Language of Qlik Sense Client could be change by changing the browser´s language or if you add the suffix /language/xx to the URL, e.g. /language/en for English or /language/fr for French.
Regarding b)
Each field in the data model has one single field name. If you are using field names in your visualisations this field name is shown by default, also in the current selections bar. This is one of the reasons why it makes sense to use master items. Here you can specify (in one of the newer versions) a dynamic label expression, which could e.g. load the correct field name to be displayed from a mapping table.
Regarding c)
If you want to have your data multi-lingual (e.g. show shipment type in the current selected language) you need to include all the different values in different languages in the data model. There are different techniques to store the data (column-wise, row-wise, linked table, ...). This would go a little bit too far beyond here. If you need to realise point c) you should work with an experienced Qlik expert.
Please mark helpful / correct if applicable.
