How to pass Organization ID while auto-triggering custom Packing Slip report on OSP Shipment?

I have created a custom BI Publisher Packing Slip report that is part of a Job Set configured to auto-trigger upon OSP shipment confirmation. The setup works fine when I manually run the ESS job and select the Organization from the LOV. However, when the job is auto-triggered during the OSP flow, I receive the following error:

You must provide valid value for the Organization attribute.

Can someone guide me on:

• How to correctly pass P_ORGANIZATION_ID when the report is triggered automatically?
• Is there any specific setup required (like profile options, value sets, or mappings) for passing parameters in auto-triggered job sets?
