How to avoid having the packing slip report submitted for external integrated WMS

Summary:

When we are using 3PL systems and warehouse management is external to Oracle Fusion, how can we avoid running the pakcing slip report during ship confirmation process

Content (please ensure you mask any confidential information):

Currently we have a requirement where Order Management and Inventory management is implemented in Oracle Fusion and Warehouse Management is external system. We send shipment requests to external system and get ship confirmations back all through rest/soAP APIs.

When the ship confirmation is done, the packing slip report gets submitted as part of the process. We usually have a large number of ship confirmations happening in a short duration window, which means, thousands of packing slip reports getting submitted in a short span of time.
