3396486 - Create a sales order with API_SALES_ORDER_SRV with reference to contract does not copying pricing data

I create a Sales order using the API Sales Order (A2X). I create it with reference to a contract. When the sales order is created, it is not fetching the prices from the contract. My payload is the following:

{ "SalesOrderType"            : "OR",
"SalesOrganization": "1010",
"DistributionChannel": "10",
"OrganizationDivision": "00",
"ReferenceSDDocument"       : "40000000", 
"PurchaseOrderByCustomer"   : "API Create w. Ref to contract", 
 "to_Partner":
[       
 {           
 "PartnerFunction": "PY",       
     "Customer":"1000001"     
   }    
],               
  "to_Item":
[
{ 
  "SalesOrderItem"         : "10", 
 "MaterialByCustomer"     :
"Item 1",  
 "Material":"123GPM",  
 "ProfitCenter"     :"220000",
    "RequestedQuantity"      : "1" 
 }
