User mapping from portal to R/3

[Former Member]

Hello everyone,

Our situation is this :

We made some visual composer iviews (charts and tables) that get data from R/3.

Instead of creating users in R/3, we want to use only one public user who can only call RFC's in R/3. So how is the user mapping implemented in this situation?

Please give me detailed explanation for it or links of documentation.

I will be appreciative and all answers will be rewarded with points.

Thanks for help.

Hi,

For connecting to R/3, you need atleast one user account in R/3. If the user id is same in both portal and R/3, then you don't need any user mapping. If they are different, then you can use user mapping or logon tickets. In your case, since you want to keep only one user for this connection, you can go for user mapping. Create R/3 system in portal and map the R/3 user to this system using User Administration -> User Mapping. So whenever you are trying to create any transaction iViews, you can use this system to connect which wil always use that user account only.

Hi,

Well, you can use User Mapping if the User Ids are <b>different</b> between R/3 and Portal Server.

However, if user ids are the <b>same</b> on both Servers, then you cna use Logon tickets.

For now, user mapping should do. All you have to do is, create a user on portal and his user id to the R/3 user id you have created.

In addition and from a maintenance perspective you could do a: Portal Group to R/3 UserMapping.

This will then automatically map all Portal Users in the Portal Group to the one R/3 user in the back-end. This saves effort when new users are created on the portal you don't have to map them all.

This method is also proposed by SAP for mapping to MDM for example.

NOTE: When you choose this you cannot trace the user in the back-end because

this back-end user is shared. If this is not a problem for your scenarion then I would say go for it.

Ali,

Have a look at this SAP Help website.

This tells you how to configure Single Sign on to SAP System using SLT and usermapping.
