Which field in Oracle SO/Delivery maps to Plan to location on order release or substitute location I

We are in OTM 6.4.1 and EBS 12.2.5 versions. We would like to send alternate ship to locations to OTM.

For example,

Source: Los Angeles, CA

Destination: San Francisco, CA

However customer doesn't want us to deliver us in San Francisco, CA. Instead they provide us an alternate ship to location in San Hose, CA. Which field should we populate in Oracle to populate the "plan to location id" in OTM? We don't want to change the ship to San Jose, CA. We want to retain that but just want to deliver the shipment to San Jose, CA.

On analyzing the integration guide, there is no mapping for Plan to location ID (for standard integration). There is only a substitute location ID mapping at location level. Any idea which field in Oracle EBS will populate substitute location? (attached mapping from integration guide)
