Dynamic Attribute in Loyalty Management

Hi,

I am facing issue in using Dynamic attributes in Loyalty Management.

I added one dynamic attribute in Loyalty Program.

Now i created a membership using the above created loy program and a member.

Now how can i use or update Dynamic attribute based on member activity.

There is a assignment block for Dyn attribute on membership page but its not getting populated with any attribute.

I have read most of the documentation on SDN but none exactly talks about this scenario. All are discussing that dyn attributes can be used,, but how we can use it in membership ,, nobody has written about it.

Thanks for the help in advance.

Regards

Vishal
