Existing customize program is using Class CL_BCS to perform email sending. And im using method SET_SENDER to set the mail sender id. Then existing prog is using CL_SAPUSER_BCS=>CREATE to get the sender id and convert to First name and last name and eventually display as sender.
Im using CL_SAPUSER_BCS=>CREATE and prob facing now is, the method is just accept SAP user id but not others. But for my case, the sender might not necessary a SAP user id.
So could u guys please comment if there other way to set the sender id like internet mail address(yahoo id) instead of a valid SAP user id?
