A separate server-side RAM-sizing for interactive portal users is not required in this case, because allowance has been made in the preceding subtopics for this RAM sizing. To explain:

Concurrent interactive portal user workload consists of multiple remote-client BI Portal users placing a load on the server-side BI Portal webapp and SQL-Server. Hence, “Sizing for Concurrent Users” sizes for the workload placed on the server-side components by the remote interactive portal users. Allowance for this had been made in the preceding DWD/Scheduler and BI Portal Webapp sizing discussions.
