Business Rules Validation: Must have one of the following values

Question

Hi All

I am trying to validate an attribute in MDS 2012 using the following Rule

Condition: If Attribute is Blank

Action: Must have one of the following values

i am supplying a domain attribute here and so the question is, is this a static list defined at "design time"

or

can i define a relationship between the member being validated and the members in the action values list?

Answer 1

The validation against a domain attribute is not static its evaluated when the rules actually run.

Answer 2

I do not think that must have one of the following values is dynamic or can reference another entity as if were a foreign key. 

If the attribute you want to validate has been defined in the model as proper domain attribute -  i.e. if you have selected the Domain-based option when you created. Why don't you create a business rule that checks is the attribute is blank, with an is required action or is not valid action.

Something like:

If [attribute] is blank

The [attribute] is required

or 

If [attribute] is blank

The [attribute] is not valid

Kind regards,

M
