auth settlement program

[Former Member]

can anyone explain how Credit card settlement happens from a technical point of view, I know it happens during invoice save , and how tables are copied from sales order to invoice, what is the user exit (program?) where the FPLTC table vales is copied to settlement table(CCSETEXD) to be sent to interface for response??

(or maybe it is copied from CCAUT (authorization structure from sales order))

Being a functional guy can someone highlight What is difference between Internal, transparent , database table and what are used in userexits? Can function module be changed or only user exits?
