PPA charge not appearing on Customer Invoice

Hello,

Currently we are using IFS Cloud and our customer invoices dont have the Prepay and Add charge that is added to our shipments. We use the invoice report to create invoices, not the collective invoice, which did have the PPA charge appear on the invoice.

How can we fix this? We currently have create customer invoice set as a batch job but will switching to the create shipment invoice fix this issue? or does the shipment invoice have different fields/parameters as the customer invoice? We dont want to lose the charges and the original information the customer invoice has
