TMT Memory module, how does it work ?

Hi, I’m using TMT (Target Monitoring Tool) version and I want to use the memory display feature.
I have RTK level 3 diagnose level enabled but in the Memory parameters I don’t see any Pool as described in the help. When I try to apply changes to any bar, line or pie chart selection I get the message: Pool data has not been initialized.
I don’t know what pool data is and if I have to include some code in my OAT program in order for the memory module to work.
Even with these apparent errors I get some bar charts but I don’t know what they reffer to as their botton labels say: R1 R2 R3 R4 R5. I don’t know if they are working either because I don’t see any movement (should I see any ?).
