Primary Purpose of a Display Business Rule:
Example of a Display Business Rule:// Runs before the form loads
(functionexecuteRule(current, gScratchpad) {
gScratchpad.manager_name= current.manager.getDisplayValue();
})(current, gScratchpad);
This scriptretrieves the manager’s namefrom the server andmakes it available on the client-sideusingg_scratchpad.manager_name.
AClient Scriptcan then useg_scratchpad.manager_nameto display the manager’s name in a fieldwithout making another server call.
