The 4 modules you mentioned are part of the Financials family.
When you buy a license, you do it for the family and this includes all modules.
Completing a licensing screen does not constitute a license agreement. It simply registers your products as active. The only way to set up a license agreement is to purchase Oracle E-Business Suite products through the Oracle Store or an Oracle sales representative. You should have complete information about your product license before you complete the licensing screens.
