Me too!

We do this all the time (or approximate it in the AS/Set CASE tool).  We
usually have four levels of errors:  1)  A fatal error that needs to message
*SYSOPR and ends the program; 2)  A top-level error for which it would be
useless to validate dependent data (e.g., it's foolish to validate a ship-to
number if the customer number was invalid); 3)  The flow-through errors you
discussed; 4)  Warnings (sometimes requiring an F-Key, password, or signature
override).
