I've read on this expert forums that Portal UME can be configured to use <b>exactly one single</b> ABAP System (say R/3) as a User Data Store. I know that multiple LDAP's can be used at once.
So my question: is this true that the connection of multiple ABAP Systems at once as User Data Stores is not technicaly possible and can anobody give me some links and literature that confirms this. Except the SAP Help. I've already read everything there.
