SAS Enterprise Miner 14.1 Decision Tree node is not using all records in training

We are using SAS Enterprise Miner 14.1. I have the below question for SAS Enterprise Miner. I am not sure where to get help, but I want to start from here. If you need more information, please let me know!

I am simply connecting a Data Source node to a Decision Tree node. When I create the data source, I set it up to not to create a sample and the data role is RAW. When I set up Decision Tree node, I use everything by default, except that for Interactive part, I set up by None for sample part. I click RUN, the results show that only a sample was used for the Decision Tree node (see the log below, 2328740 out of 3195296 training cases are shown in the root node). Then I open the Interactive Tree, it shows the same, only part of the records are used in the root node, not all the records. I am not sure why only part of the records are being used for the Decision Tree node. Is this because of some sort of memory limitation, or the Data Source or Decision Tree node property settings that I am not aware of? Thanks you for sharing your thoughts.

I googled it online, it seems an option on max no. of observation was available in old releases, but I tried it and it does not resolve above issue in Eminer 14.1 version. Thank you for help!
