ABAP_DESCRIPTION A remote-enabled function module DEMO_RFM_LOGON_DATA>> is called with the destination NONE > using the RFC interface. The logon data user name, client, and logon language of the corresponding RFC session> are provided implicitly. To demonstrate that the logon language> of the RFC session is set by the language of the text environment> of the caller, it is set to a language other than the logon language of the caller before the call with the statement SET LOCALE LANGUAGE>>. In the called RFM the language of the text environment of the RFC session is also changed and is then also different to the logon language. If the function module DEMO_RFM_LOGON_DATA> is called remotely again, the RFC session is reused with the existing logon data. Changing the language of the text environment again in the caller would no longer have any effect.
