I wish to call a function module from an external system, namely
HR_GETEMPLOYEEDATA_FROMUSER and i wish to default the
user name field to the user currently logged in to SAP i.e. sy-uname.
Is there a way to pass the value in to the fm so that the call
runs with the value of username = sy-uname.
i.e. what should ??? be in the following call from the remote system :
CALL FUNCTION 'HR_GETEMPLOYEEDATA_FROMUSER'
username = ???
Hope you can help! Many thanks in advance!
