Retrieve Disbursement Acknowledgements ESS job is not working without payment file ID

Summary:

As per oracle documentation, Retrieve Disbursement Acknowledgements process can be run as a standalone ESS job. However, if this ESS job is run without a payment file ID, this job is not picking any of the ACK files to process.
Given that we will have around 10-15 payment runs every day, it is not humanly possible to keep retrieving the ACK files manually, so we need to schedule it to pick all ACK files received at a given point in time. In addition, the bank sends us ACK1 and ACK2 files and both files need to be processed in a timely manner.
