Yes, it could result in lots of _logical_ reads, since the page should
be in memory after the first read. But logical reads aren't nearly as
costly as physical ones.

Your service program could also check to see if it's already got the
data for the custom on-hand before reading it again.

You'd call other getters for the additional information you'd need for
the message.

If you find out that you often need the same group of fields, then you
could build a single getter that returns a DS (whose structure doesn't
change ;)

DO NOT SIMPLY CREATE GETTERS/SETTERS FOR EVERY FIELD!

Instead, have business logic routines that you can call.

Do this:

if CUSTOMER_IsOverCreditLimit(wCustomerNumber:wSaleAmount);
  //display message?
endif;

Instead of this:
if wSaleAmount > CUSTOMER_GetCreditLimit(wCustomerNumber);
  //display message?
endif;


Isn't that going to result in a load of file reads for the same customer? What if I other customer information must be used in the message?
