I have currently a problem with the logon language of MII (to sap erp).
I call a function module with rfc and I get standard error messages in englisch which is not really a problem for me but the messages are saved and a user has to look at them.
What I did: I changed the logon language in MII SAP server editor to "DE" but the messages are still in english. If I call the function module direct in SAP with my user with the german logon language the error messages are saved in the german language.
Thanks for your help.
