[ProjectionName].ACCESS_FAILURE: Arguments used to execute current operation are not allowed

Getting a strange error when trying to use two INT REST APIs which are working fine through Aurena. But not working when I try to run it through Postman using basic authentication.

Could you kindly go through the below scenario and help me resolve the issue?

Below is the Scenario:

• I am trying to deliver customer order lines using the available rest APIs from the documentation.
• I am using IFS Apps 10 Update 16

• I am trying to use REST API with basic authentication
• REST API - https://[ifshost]/int/ifsapplications/projection/v1/DeliverCustomerOrderLines.svc/DeliverLines
• Payload

  1{
  2    "OrderNo": "M1132",
  3    "LineNo": "1",
  4    "RelNo": "4",
  5    "LineItemNo": 0
  6}

• Authentication - Basic

• Projection DeliverCustomerOrderLines.svc is included in compatibility mode and permissions are properly set (the same user name and setup works fine for other REST APIs)

• Error:

  1{
  2    "error": {
  3        "code": "DATABASE_ERROR",
  4        "message": "Database error occurred. Contact administrator.",
  5        "details": [
  6            {
  7                "code": 20181,
  8                "message": "ORA-20181: DeliverCustomerOrderLines.ACCESS_FAILURE: Arguments used to execute current operation are not allowed."
  9            }
  10        ]
  11    }
  12}

• Same thing happens for another REST API as well
• REST API - https://[ifshost]/int/ifsapplications/projection/v1/DeliverCustomerOrderLineWithDifferences.svc/DeliverNonInvLineWithDiff
• Everything else is same and the Error will look like the following:

  1{
  2    "error": {
  3        "code": "DATABASE_ERROR",
  4        "message": "Database error occurred. Contact administrator.",
  5        "details": [
  6            {
  7                "code": 20181,
  8                "message": "ORA-20181: DeliverCustomerOrderLineWithDifferences.ACCESS_FAILURE: Arguments used to execute current operation are not allowed."
  9            }
  10        ]
  11    }
  12}
