If you have ever been banging your head against the wall trying to figure out why my Sold-To party would not copy to my service order (like I have). There is a table called TPAER_PM. This table defines by PM/SM partner determination procedure which partners should be copied.
Strangely, only some of my partners were selected by default for copy. No idea why. In addition, there is a report you can use RIPACOPY. This report will copy all of your procedures and partners into the table. You will still need to add an X into any column that you want to copy. So make sure you visit SE16N and set these values if you want them copied from the sales orders.
