Hi,

I want to know if we can update customer attribute for a offer flow in CDH framework. 

The context of the question is as below:

We are setting some customer attribute (Customer phone number)  inside strategy for an outbound campaign. We have applied a Volume constrain in that campaign. But after processing in the SMS table we are getting the actual value of customer phone number from DB, not the updated value set in the strategy. 

if we don't use volume constrain everything is working fine. 

our understanding is when Pega is applying the VC, it is fetching the actual customer data again from DB , that is overriding the customer phone number set in Strategy.

Out plan is to set the logic in Offer flow itself, so that even after VC, we can have the customer phone number as per out logic.

When we are trying property set the customer attribute, we are getting the exception during checkin of the offer rule.

please let us know if it is a general validation or it is an environmental issue.
