A while ago, Daniel Wroblewski posted a blog about using the portal dynamic resolution service. It can be seen here (New in Portal SP11: Dynamic System Resolution). Following is an example to support multiple backend SRM systems. First we need to make some folders in the PCD to hold the system definitions. Here is an example:The important thing is the ID – this is case sensitive. Now we can make some systems in this folder. Here’s an example:Once again, the ID is important. In this case we make the first system sap_srm1, the second one sap_srm2 etc. You will probably use “SAP System with dedicated application server” or “SAP system with load balancing”. Enter connector, ITS and WAS values as normal.
