How to retrieve Requisition Distribution code_combination_id using REST API

Content

All,

When I use Get all distributions REST API

(https://docs.oracle.com/en/cloud/saas/procurement/19b/fapra/op-purchaserequisitions-requisitionheaderid-child-lines-requisitionlineid-child-distributions-get.html)

The REST API returns only:
- RequisitionDistributionId

- Quantity

- DistributionNumber

When I use getPurchaseRequest SOAP API

(https://docs.oracle.com/en/cloud/saas/procurement/19b/oeswp/business-object-services.html#purchaserequestserviceversion1-d17024e2951)

The API returns info only when a po_header_id is supplied, and I need the info before the PO is created

Appreciate any idea!
