Contact Person for Vendor in SRM/CUA

Question

Hello SRM Expert,
We are using Central user administration (CUA and like other system SRM is connected to CUA. I am getting the error 'Central system not accessible' while creating the employee (manage business partner) for business partner (Vendor). When we remove CUA then the error disappear.
Could you please let us know would be our approach for creating employee for vendors (for bidding, auction etc..).
Steps for Reconstruction    
1. Login to SRM
2. Click on Manage business partner (BBPMAININT)
3. Look for Employee for Business Partner 'Create' option and create a  employee for one of the vendors.
4. You will get the message Central 'System not accessible' .
I know one approach where I can create a SU01 in advance from CUA  and then in manage business partner use this user but this is very long approach looking at the number of vendors we have. Is there a simpler way ?
Thanks,

Sorry yes it is not specifically about external users. You should review the note again, particularly scenario 2.
Essentially the note explains that, in a CUA environment, to create a user for an external contact person you need to create the following entry in table "BBP_CUST":
Key = "EBP_CUA_SCENARIO"; Value = "ACTIVE".
If you do not want to user table maintenance you can create the entry via the following IMG menu path:
Supplier Relationship Management > SRM Server > Technical Basic Settings >
Deactivate User Access to Solution Manager.
(Ignore the transaction title this transaction is essenatially maintenance of table "BBP_CUST").
Then you must ensure that the user specified on the RFC Definition for the CUA client has authorisations to create users IN THE CUA CLIENT, (it already has authorisations to create in the SRM client). This lack of authorisation is probably the reason for your error message.
