Passing customer id(logged in user) to BAPI

Question

Hi,
I am creating a sales order application where in i have to pass the user id (customer  logged in through portal) .
I have made the MODEL RFC as ticket, and meta data as user id password where i have passed the service user and password.
Now my problem is that there will be 'N' customer ids in Portal but we are not creating any customer ids in SAP ECC. We are planning to pass the user id of portal logged in user to ECC (which will be customer id) and get the data based on the customer id passed.
Question is how do i pass customer id to BAPI, ? Do i have to make the MODEL JCO as user/password or ticket should be fine as i am getting information for only customer logged in Portal ?
How and where do i write the the following piece of code ? Should it be in wdDo init() or in the execute method of Controller ?
try{
IUser user = WDClientUser.getLoggedInClientUser().getSAPUser();
IUserAccount[] acct = user.getUserAccounts();
if(acct[0] != null)
String strUserid = acct[0].getLogonUid();
customer=strUserid.substring(0,strUserid.indexOf("."));
if(customer.equalsIgnoreCase(customer))
wdContext.currentYOURRFC_InputElement().setCustomer(customer);
}catch(Exception ex)
ex.getMessage();
Should the above code be in the component controller before i execute the BAPI ?
your help is appreciated.
Regards

Hi Portal Newbie,
Your tickets and userid/password works as following:
Tickets: When u select SAP logon ticket (SLT), EP generates a ticket with the user id of the logged in user, attached to the ticket. Now when it reaches R/3 it will check for the same user id. If no such user id is exits it will throw an error. To over come this u can define a reference system where u can do the user mapping.
UIDPD: When u select this option u have to manually enter the user id and password in JCo. So when a EP user logs in the UID and password mentioned in JCo will be passed, not the EP user id, and R/3 will look for that user and execute the BAPI. And i guess u dont want that.
Solution:
As far as i have understood u dont want the same number of users in EP and R/3, (might be a licensing issue) and want only a few user IDs in R/3.
1. Select UIDPD in JCo, and in your BAPI add another field like "user_id" through which u can send the user id to R/3 and execute a query which shall return the value corresponding to that particular user. [issue: there is a limit to the JCo connections created for a user.] Also there is an api to handle JCo connection in webdynpro. There u can set the user id, password and client number. But here also the user id that you set should be present in R/3.
2. Select SLT in JCo and configure a reference system. You have to perform user mapping for every user. Now when a user logs in the ticket will contain the user id of EP and also the one u have mapped, ie the R/3 user. Make sure the R/3 user id exists in R/3. Now the sy-unam in BAPI will contain the R/3 user id. I guess there is an option to retrieve the EP user id from the ticket, but im not sure.
In your kind of scenario its always recommended to have same number of user ids in EP and R/3. If user names are same then there is no need to configure reference system.

ps: reference system is just a system that we create in EP but in UME settings we have to specify this system as the reference system.
