Languages are imported into the system in language
packages. Each language package can contain one or more transport
requests.
To make it easier to organize multiple transport requests for the language
export, they are grouped in a language package. Technically, these language
packages correspond to Support Packages, such as SAP R/3 Support Packages or
SAP HR Support Packages.
This means that a language export also involves the creation of transport
requests and their inclusion in a language package.
You export languages in a user dialog in transaction SMLT_EX.
