How to put hold on all collections activities for Invoices with open disputes,while using Strategies

Business Requirement is to implement collections strategies which include manual collection tasks and automated dunning tasks. Strategies need to be designed such that, a first dunning reminder will always be issued on Day 30, second reminder on Day 44 and Final reminder on Day 58, regardless of customer profile or collections score.

We need that any invoice marked as in dispute is excluded from collections activities (both open balance calculation for strategy selection and dunning letter) until the dispute is resolved.

• Automatic Credit Memo creation is not being used for disputes as not all disputes need one
• Most relevant data point to match the above requirement is 'Account Age of Oldest Overdue Transaction'. Please confirm if this data point considers disputes which are not yet approved.
