Hello Carl,

You can use YourBusinessRule.HostObject property. This stores a reference to the object responsible for creating YourBusinessRule object. One thing to keep in mind, though, is that this reference is stored as ImmBusinessRuleHost type. IOW, you'll have to cast it to your business object for access to the custom methods you're probably looking to implement.

For references to other/multiple objects, you're best off creating them from within the business rule object. We've also used mmBusinessProcess to coordinate multiple business objects' methods.

Hope that helps,

>How would I call one or more business objects from within a business rule class? There are some cases where data validation is based on a number of conditions that can only be determined by using other business objects accessing different database tables. For instance, I want to do something like this within business rule:
>
>

>Public Function ValidateCreditRating(ByVal creditRating As String, ByVal creditCode As String, ByVal customerID As Integer) As String
>        Dim message As String = Nothing
>        ' check rating
>        If creditCode = "Z" Then
>            Dim ratingGood As Boolean
>            ratingGood = Me.oCreditCheck.CheckRating(creditRating, customerID)
>            If ratingGood = False Then
>                message = "Credit rating too low."
>                Me.AddErrorProviderBrokenRule("CreditRating", message)
>            End If
>        End If
>        Return message
>    End Function
>
