Hi All,

This is my Today's scenario:

1 Productive SAP ERP 6.06 link with 1 Productive SAP EP 7.31

ERP 6.06 -> EP 7.31

Now, we have a new scenario, because we installed SRM 7.13.

And my company want to have only one Portal.

New Scenario:

ERP 6.06 -> EP 7.31 <- SRM 7.13

Is possible connect two backends to 1 Portal ?

Thanks and Regards,

Juan.

Hi Juan,

Portal UME can not point to 2 ABAP data sources (ERP and SRM in your case) at the same time for authentication.


As your Portal system is already connected to ERP system as data source for authentication, you cannot use  Web AS Java data source or LDAP data source in your case because switching of data source from ABAP to Java can lead to UME inconsistency.


However, you can use the concept of CUA (Central User Administration).

Using Central User Administration, you can maintain user master records centrally in one system. Changes to the information are then automatically distributed to the child systems.


So, once CUA is configured in your landscape, you just need to point the Portal UME to one of the ABAP client which will act as a CUA client, and rest of the back end SAP systems clients (SRM system etc.) will act as child clients to CUA.


Please go through the following threads:

Hope this helps!!!

Thanks Anurag for the approach.

But, I have another question now regarding CUA linked to ERP and SRM.

How about the UserID? They need to be different on ERP and on SRM, for example:

ERP: User

SRM: User1

Because, when I try to connect to Portal, the credentials need to be different?

How the system knows which server I want to connect ?

or is the Users permissions who determine the connection?

Thanks in advance

Hi Juan,

All the user master records would be maintained in CUA system and from there they would be distributed / pushed to the specidfic child systems based on ALE approach.

Now, suppose you have User A in ERP system and User B in SRM system and both the back end systems are connected to Portal system.

Now, when User A logs on to the Portal, the authentication will be done through your CUA system and the user will be able to access the ERP system functionality based on the ERP system specific portal roles provided to the user and through single sign on mechanism between the portal and ERP system.

Similarly, when User B logs on to the Portal, the authentication will be again done through your CUA system and the user will be able to access the SRM system functionality based on the SRM system specific portal roles provided to the user and through single sign on mechanism between the portal and SRM system.

In case, User C wants to access both the back end systems, ERP and SRM , the user id of User C has to be same in both the systems and I think that can be achieved by CUA system.

So, the authentication in portal will be performed by CUA system and then the user can browse the respective back end systems based on the roles provided to them.

Thanks Anurag,

I did the CUA from ERP... and Portal works with ERP and SRM !!!
