Trading Partner not receiving Control Message despite Celigo showing as Accepted showing control flow run successfully

I’m using this guide to send control messages to trading partner: Generate acknowledgment for an EDIFACT transaction – Celigo Help Center

this is the data in the celigo listener coming from orders flow:

{
  "UNB Interchange control reference": "100000085",
  "isSuccess": true,
  "functionalAcknowledgement": 7,
  "failedMessages": 0,
  "successfulMessages": 1,
  "totalMessages": 1,
  "unbSenderId": "Sender",
  "unbReceiverId": "Receiver",
  "Message": [
    {
      "UNH Message reference number": "1085",
      "Doc type": "ORDERS",
      "isSuccess": true
    }
  ]
}

My file definition setting for control:

My flow:

In my celigo edi activity dashboard it is shown as accepted but the trading partner not receiving any control message. please help what’s wrong in the flow.

Hi @Ajay_Sankar_J did you mock the flow step ‘Send Contrl Msg’ with your test FTP and check if the file is generating as expected with the right data and the file name?
