This batch process is used to process and activate the payment correction cases which are used to manage over and underpayments when CPM financial product deliveries (Invoice, Attendance, Contract and Placement) are configured not to use rolled up reassessment. The process retrieves all the payment correction cases created for the product delivery cases in each of the four financial product deliveries. The process then processes and activates the payment correction cases using the API 'paymentCorrection'. This batch process would be scheduled to run daily before the financial batch processes 'GenerateInstructionLineItem' and 'GenerateInstruments' are run.
