Validation rule expressions are used primarily to validate target-system account balances. The expressions, which use standard expression capabilities of Microsoft VB Script, return a True or False result.
For example, the following expression returns True if the value of 1000.100 (a target account) plus $100,000 equals the value of 1000.400 (another target account) and false if it does not:
|1000.100| + 100000 = |1000.400|
Validation rule expressions can incorporate validation rule functions: the Hyperion Enterprise lookup function (when integrating with Hyperion Enterprise) or the multi-dimension lookup function (when integrating with multi-dimension target systems).
