Validation Rules
In planning models, you can define valid ranges of data that allow data entry and planning operations.
Validation rule lets you define the allowed member combinations across dimensions to prevent improper data entry and planning operation in stories based on this model. For the dimensions you define in a validation rule, only the member combinations that you specify as allowed combinations can pass validation.

ญExample
Let's say that certain products are allowed to be sold in limited locations.
You create a validation rule between the product dimension and location dimension
members. Planning users can do planning only for the allowed combinations of products
and locations.
