ISG_SERVICE_EXECUTION_ERROR Failed Data Security validation for user

I am using EBS 12.2.10 with database 19c (19.10.0.0.0) I am invoking Rest API but it is throwing following error:

{

    "ISGServiceFault": {

        "Code": "ISG_SERVICE_EXECUTION_ERROR",

        "Message": "Error occurred while executing the web service request",

        "Resolution": "System error, please see service log trace for details.",

        "ServiceDetails": {

            "ServiceName": "processtransactions",

            "OperationName": "transactmoveorder",

            "InstanceId": "0"

        }

    }

}

In service monitor following message is appearing:

Adapter error - null : Data Security Validation Failed. Validation for Data Security failed. Failed Data Security validation for user "USERNAME" and API "PLSQL:PACKAGE:PROCEDURE

What does it mean and how to resolve it?
