DataSource 2LIS_17_I3HDR not loading all order types in setup tables

I am trying to setup data source 2LIS_17_I3HDR. I have initialized the setup tables and I am only getting 609 records in RSA3. The problem is that all the records are from only two order types. I have run the setup table initialization wide open so i'm not sure why the setup table only contains a subset of our orders.

Obviously we have numerous other order types that I am expecting to be loaded into the setup tables (AFIH has around 180k entries). Where can I configure which orders get loaded into the setup tables?

Thanks,

Chris
