3730144 - Field RequestedDeliveryDate is ignored by API Sales Order (A2X, OData V2)

When creating a sales order using the API Sales Order A2X OData V2 (API_SALES_ORDER_SRV), and including the items and their schedule lines, the field RequestedDeliveryDate on the schedule line is ignored and the system uses the sales order creation date.

SAP S/4HANA Cloud Public Edition

Send a POST request to the endpoint: <host>/sap/opu/odata/SAP/API_SALES_ORDER_SRV/A_SalesOrder

Use the following payload:

{
  "SalesOrderType": "OR",
  "SalesOrganization": "1010",
  "DistributionChannel": "10",
  "SoldToParty": "10100001",
  "to_Item": {
    "results": [
      {
        "SalesOrderItem": "10",
        "SalesOrderItemCategory": "TAN",
        "Material": "TG11",
        "RequestedQuantity": "10",
        "RequestedQuantityUnit": "PC",
        "to_ScheduleLine": {
          "results": [
            {
              "ScheduleLine": "1",
              "ScheduleLineOrderQuantity": "10",
              "RequestedDeliveryDate": "2026-04-16T10:00"
            }
          ]
        }
      }
    ]
  }
}

The Schedule Line entity can only be created as a single entity. The prerequisite is that the item already exists, so it cannot be created at the same time (same request) as the item.

Firstly create the sales order and its items, and then, on a subsequent request, create the schedule line containing the necessary RequestedDeliveryDate.

Payload examples for schedule line creation can be found here: Create Schedule Line for Sales Order Item (Create Single Entity) | SAP Help Portal

Note: deep insert requests cannot be used for schedule line creation.
