Add SO Allocation with PUT Request on SO Creation

@Dmitrii Naumov , that worked. Thank you!

 @Dmitrii Naumov  Here i posted my Sample Json for SalesOrderDetail.

I have skip the Quantity but it’s still creating extra allocation without serialNo and   two allocation with SerialNo due to which Quantity of item updated from 2 to 3.

@Rahulbcomm , what I found out was that I had to create lines in one call, get the SOLine and SOLineSplit IDs, and then UPDATE with a serial number.  I wasn’t able to do it in a single call, unfortunately.

@Yuri Karpenko 

thanks for update,

do you mean that we need make separate update call for each allocation line?

if  yes can you please help me to built URL for it.

@Rahulbcomm , your URL would be:

https://company.acumatica.com/entity/Default/20.200.001/SalesOrder?$expand=Details,Details/Allocations

And your body would be:

{
      "id": "764e3516-4f71-ed11-8193-1289eaf13cab",
      "Details": [

{
          "id": "7c4e3516-4f71-ed11-8193-1289eaf13baz",
          "Allocations": [

{
              "id": "88396a89-712f-42a6-be26-bf1bc24377dd",
              "Allocated": 
{
                "value": true
              },
              "LotSerialNbr": 
{
                "value": "8276347"
              }
            }
          ],
          "WarehouseID": 
{
            "value": "MAIN"
          }
        }
      ]
    }

I do it for each line / serial number separately. But you might be able to do so in a single call for all of the lines that must be allocated.

@Yuri Karpenko  

Does it not works for you in a single call of sales order update? I am trying to update whole salesorder with  all the salesorderdetails and allocation belings to it.

@Rahulbcomm , it should. My set up is different where it’s easier for me to do multiple calls, but try with a single call, and it should work for you en masse.
