BI 7.0 data load issue: InfoPackage can only load data to PSA?

Question

BI 7.0 backend extraction gurus,
We created a generic datasource on R3 and replicated it to our BI system, created an InfoSource, the Transformation from the datasource to the InfoSource, an ODS, the transformation from the InfoSource to the ODS. 
After the transformation creation between the InfoSource and the ODS is done on this BI system, a new folder called "Data Transfer Process" is also created under this ODS in the InfoProvider view.  In the Data Transfer Process, in the Extraction tab, picks 'Full' in the field Extraction Mode, in the Execute tab, there is a button 'Execute', click this button (note: so far we have not created InfoPackage yet) which sounds like to conduct the data load, but find there is no data available even if all the status show green (we do have a couple of records in the R3 table). 
Then we tried to create an InfoPackage, in the Processing tab, find 'Only PSA' radio button is checked and all others like 'PSA and then into Data Targets (Package by Package)" are dimmed!  In the Data Target tab, find the ODS as a target can't be selected!  Also there are some new columns in this tab, 'Maintain Old Update Rule' is marked with red color 'X', under another column 'DTP(S) are active and load to this target', there is an inactive picture icon, that's weird since we have already activated the Data Transfer Process!  Anyway, we started the data load in the InfoPackage, and the monitor shows the records are brought in, but since in the Process tab in the InfoPackage, 'Only PSA' radio button is checked with all others dimmed that there is no any data going to this ODS!  Why in BI 7.0, 'Only PSA' radio button can be checked with others all dimmed?
Many new features with BI 7.0!  Any one's idea/experience is greatly appreciate on how to load data in BI 7.0!

Answer 1

You dont have to select anything..
Once loaded to PSA in DTP you have the option of FULL or DELTA ,full loads all the data from PSA and DELTA loads only the last load of PSA.
