I need to define two rosters, but they should be nested: The first one has the ID number of the mother, and the second one has several lines for all children of the woman.
The developers of this application released a user guide which is very comprehensive when it comes to the way the software works. I've downloaded and opened the PDF file and there were instructions related to rosters and the data that can be added.
Use the following link to download user guide: http://www.census.gov/population/international/files/cspro/start50.pdf
