I want to create a Business Rule based on a Child Table

Posted on by Community Power Pla...

I have a Parent Table named "Request" and a child table named "Tasks". The relation is 1 Request : N Tasks. There is a "Request Status" field in the Request table, on which I want to enforce a business rule as follows

=> If at least any one of the Tasks related to the request is "Open", then "Request Status" cannot be "Completed" .

If this is not possible is there a work around?

I am unable to find a solution for this. Any help is much appreciated.

Thanks...

Hi @Anonymous,

One way to achieve your business logic is to add a whole number column to Requests that represents the Count of Open Tasks. A business rule can then check whether the value is greater than 0.

To keep the count up to date, you can use a Dataverse workflow on the Task table to increment or decrement the count on the Request table whenever the Task status changes.

Here is a similar example from CRM 2011 but still holds true today.
