Orchestrator - Issue with generic format

Hi,

Can you please help with the generic format?.  How to input generic format for single and multiple rows in orchestrator (6.0.2 version).  I have created orchestration program and successfully able to create order with JASON format but when I tried to generate order for generic format getting errors.  Here it seems to be i am missing something for generic format. 

I am doing below steps

1. Select JASON, then format and used below format

{

      "FromBranch": "ABC",

      "ToBranch": "XYZ",

      "ItemNumber": "ITEM1",

      "QuantityOrdered": "2",

      "RequestedDate": "02/28/2019"

}

After running order not generated getting errors. 

I could able to generate with below JASON format.

{

  "inputs" : [ {

    "name" : "FromBranch",
