Field Masking for Web Dynpro ABAP – Role based masking scenario in Personnel & Organization application

Introduction

In this blog post, we will learn how to mask “Social Security Number” and “Date of Birth” of Employees in Personal Data section of Personnel & Organization (HRPAO_PAOM_MASTERDATA) application.

A PFCG Role will be used for the authorization check which will allow users with the specified role to view the field value. If a user does not have this role, it means the user is not authorized and data will be protected either through masking, clearing, or disabling the field.

The end result for unauthorized users will look like below:

Prerequisite

Product “UI data protection masking for SAP S/4HANA” is used in this scenario to protect sensitive data at field level and must be installed in the S/4HANA system.

The product is a cross-application product which can be used to mask/protect any field in SAP GUISAPUI5/SAP FioriCRM Web Client UI, and Web Dynpro ABAP.

Let’s begin

Configuration to achieve masking

Logical Attribute is a functional modelling of how any attribute such as Social Security NumberBank Account NumberAmountsPricing informationQuantity etc. should behave with masking.

Configure Logical Attribute

Follow the given path:

SPRO -> SAP NetWeaver -> UI Data Protection Masking for SAP S/4HANA -> Maintain Metadata Configuration -> Maintain Logical Attributes

Social Security Number

Birth Date

Maintain Field Level Security and Masking Configuration

Here, we will define how masking will behave with the logical attribute that we created in above step.

Follow the given path:

SPRO -> SAP NetWeaver -> UI Data Protection Masking for SAP S/4HANA -> Data Protection Configuration -> Maintain Field Level Security and Masking Configuration

Follow below mentioned steps:
  • Click on “New Entries” button
  • Enter “Sensitive Entity” as “LA_SOCSECNO” and press “Enter” key. “Description” and “Application Module” will get populated in corresponding fields
  • Check “Enable Configuration” check-box
  • Select “Role Based Authorization” option
  • Enter “PFCG Role” as “/UISM/PFCG_ROLE“. In this example, we have used a blank role “/UISM/PFCG_ROLE”. Customers can use any role as per their requirement.
  • Enter “Field Level Action” as “MASK_ALL
  • Click on “Save” button

  • Click on “New Entries” button
  • Enter “Sensitive Entity” as “LA_BIRTHDATE” and press “Enter” key. “Description” and “Application Module” will get populated in corresponding fields
  • Check “Enable Configuration” check-box
  • Select “Role Based Authorization” option
  • Enter “PFCG Role” as “/UISM/PFCG_ROLE“. In this example, we have used a blank role “/UISM/PFCG_ROLE”. Customers can use any role as per their requirement.
  • Enter “Field Level Action” as “MASK_ALL
  • Click on “Save” button

Maintain Technical Address

In this step, we will associate the Technical Address of the fields to be masked with the Logical Attributes.

You can get the Technical Address of a Web Dynpro ABAP field by pressing “Right-Click” on the field and then click on “Technical Help” option.

Follow the given path:

SPRO -> SAP NetWeaver -> UI Data Protection Masking for SAP S/4HANA -> Maintain Metadata Configuration -> Maintain Technical Address

Follow below mentioned steps:

Under “Web Dynpro Field Mapping”, maintain technical address for following fields.

  • Click on “New Entries” button
  • Enter “Application Name” as “HRPAO_PAOM_MASTERDATA
  • Enter “Component Name” as “FPM_OVP_COMPONENT
  • Enter “View Name” as “MAIN
  • Select “Type” as “Floorplan Manager
  • Enter “Component Configuration” as “HRPAO_PAOM_MASTERDATA
  • Enter “Field ID” as “FGL2_005056A204721EE198C66EAD3AA6947F
  • Enter “Logical Attribute” as “LA_SOCSECNO
  • Enter “Description of Web Dynpro Mapping” as “Social Security Number
  • Click on “Save” button
  • Click on “New Entries” button
  • Enter “Application Name” as “HRPAO_PAOM_MASTERDATA
  • Enter “Component Name” as “FPM_OVP_COMPONENT
  • Enter “View Name” as “MAIN
  • Select “Type” as “Floorplan Manager
  • Enter “Component Configuration” as “HRPAO_PAOM_MASTERDATA
  • Enter “Field ID” as “FGL2_005056A204721EE198C6701EB0DF147F
  • Enter “Logical Attribute” as “LA_BIRTHDATE

In this blog post, we have learnt how Role-based masking is achieved in Personal Data section of Personnel & Organization (HRPAO_PAOM_MASTERDATA) application for masking “Social Security Number” and “Date of Birth” fields.
