Welcome to @cap-js/audit-logging

REUSE status

@cap-js/audit-logging is a CDS plugin providing integration to the SAP Audit Log service as well as out-of-the-box personal data-related audit logging based on annotations.

Documentation can be found at cap.cloud.sap.

Important

The information in this file is by no means complete but enables you to get started quickly. Make sure to read the provided documentation at cap.cloud.sap to get the full picture.

Preliminaries

In this guide, we use the Incidents Management reference sample app as the base to add change tracking to. Clone the repository and apply the step-by-step instructions:

git clone https://github.com/cap-js/incidents-app
cd incidents-app
npm i

Setup

To enable audit logging, simply add this self-configuring plugin package to your project:

npm add @cap-js/audit-logging

Annotate Personal Data

Identify entities and elements (potentially) holding personal data using @PersonalData annotations. Create a db/data-privacy.cds file and add the following:

using { sap.capire.incidents as my } from './schema';

annotate my.Customers with @PersonalData : {
  DataSubjectRole : 'Customer',
  EntitySemantics : 'DataSubject'
} {
  ID           @PersonalData.FieldSemantics: 'DataSubjectID';
  firstName    @PersonalData.IsPotentiallyPersonal;
  lastName     @PersonalData.IsPotentiallyPersonal;
  email        @PersonalData.IsPotentiallyPersonal;
  phone        @PersonalData.IsPotentiallyPersonal;
  creditCardNo @PersonalData.IsPotentiallySensitive;
};

annotate my.Addresses with @PersonalData: {
  EntitySemantics : 'DataSubjectDetails'
} {
  customer      @PersonalData.FieldSemantics: 'DataSubjectID';
  city          @PersonalData.IsPotentiallyPersonal;
  postCode      @PersonalData.IsPotentiallyPersonal;
  streetAddress @PersonalData.IsPotentiallyPersonal;
};

annotate my.Incidents with @PersonalData : {
  EntitySemantics : 'Other'
} {
  customer @PersonalData.FieldSemantics: 'DataSubjectID';
};

Test-Drive Locally

You've prepared everything to log personal data-related events. Let's see that in action.

Start the server as usual:

cds watch

Send an update request that changes personal data:

PATCH http://localhost:4004/odata/v4/admin/Customers('1004155')
Authorization: Basic alice:in-wonderland
Content-Type: application/json

{
  "firstName": "Danny",
  "lastName": "Joules"
}

See the audit logs in the server's console output:

[audit-log] - PersonalDataModified: {
  data_subject: {
    id: { ID: '1004155' },
    role: 'Customer',
    type: 'AdminService.Customers'
  },
  object: {
   type: 'AdminService.Customers',
   id: { ID: '1004155' }
  },
  attributes: [
    { name: 'firstName', old: 'Daniel', new: 'Danny' },
    { name: 'lastName', old: 'Watts', new: 'Joules' }
  ],
  uuid: '71fa93d9-c993-405f-ba1b-a9ef42668199',
  tenant: 't1',
  user: 'alice',
  time: 2023-02-26T08:13:48.287Z
}

In Production

The end-to-end out-of-the-box functionality provided by this plugin requires a paid-for instance of the SAP Audit Log service for customers. However, it is possible to provide an own implementation that writes the audit logs to a custom store.
