Hey https://system.netsuite.com/help/helpcenter/en_US/APIs/REST_API_Browser/record/v1/2023.1/index.html#tag-purchaseOrder on running the get purchaseOrder which will fetch all the purchase orders i am getting this error

{
  "type": "<https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.4.1>",
  "title": "Bad Request",
  "status": 400,
  "o:errorDetails": [
    {
      "detail": "Invalid search query. Detailed unprocessed description follows. Record 'transaction' was not found. Reason: INSUFFICIENT_PERMISSIONS - Missing permissions for this record.",
      "o:errorQueryParam": "q",
      "o:errorCode": "INVALID_PARAMETER"
    }
  ]
}

i have checked whether i have permission for this or not by going to Setup > Integration > Manage integration > Role. I have given permission here Can anyone help me in this?

Try adding the Find Transactions permission to the role.

Thanks @Eric B worked
