Some actions in the system can trigger the need to run some demand validation again. These actions are determined based on the validation step itself.
For example, demand that has failed past-due invoices validation should be revalidated if a payment is posted for that customer.
Note: If validation was already rejected, deliver remainder was set to zero and cannot be automatically revalidated.
When revalidation is determined to be needed then validation results, any validation exceptions, and channel demand validation status are updated. This will free-up the demand to go back through the validation processes again.

Credit check revalidation

A processing parameter was added called 'Credit check revalidation threshold percentage' to control the percent change in value of an order that should trigger credit check revalidation.
When a payment journal is posted, the credit limit of the customer changes, or when the order value percentage change is greater than the value threshold, revalidation is triggered.

Customer PO revalidation

When the customer requisition field is updated on the sales order, revalidation is triggered.

Past Due Invoices revalidation

When a payment journal is posted for a customer, revalidation is triggered.
