The When setting for a Business rule determines when it executes and has the following choice:

A
  1. Before a record is saved to a database
  2. After a record is saved

A

Business Rules

Q

Business Rules are loaded and initialized:

Q

Business Rules apply to records:

A

regardless of how they are accessed (forms, lists, web services)

40
Q

What is the difference between UI Policies and Business Rules?

Q

Every Business Rule includes:

A
  1. what TABLE to run against,
