UI Data Protection – How to mask Sensitive Key Fig...

Introduction

In this blog, we will learn how to configure masking in Analytical Queries to protect the sensitive information displayed in it. Analytical Queries are used for reporting and analysis.

S/4HANA Embedded Analytics

Analytics is one of the most typical and tangible values of S/4HANA. S/4HANA Embedded Analytics is the function for real-time operational analytics in S/4HANA. It consists of ABAP CDS Views as data source and Fiori Analytical application as the frontend. As the frontend, other than S/4HANA Embedded Analytics, SAP Analytics Cloud is available which is used together with S/4HANA embedded analytics.

Query Monitor (RSRT TCode)

The Query Monitor tests, checks, and is used to test or regenerate queries and query views, and to check or change query properties. A detailed analysis of queries can be done with the transaction RSRT (Query Monitor) in a very convenient way. With the help of the Query Monitor you can run and analyze queries without a BW front end.

To launch the Query Monitor, execute transaction RSRT.

Here, we will use Query Monitor to showcase masking of sensitive fields of analytical queries. We will configure masking through UI Data Protection Masking for SAP S/4HANA 2011 solution based on Role Based Authorization Control (RBAC) concept.

Prerequisite

UI data protection masking for SAP S/4HANA is a solution for selective masking of sensitive data on SAP S/4HANA user interfaces – SAP GUI, SAPUI5/SAP Fiori, Web Dynpro for ABAP, and Web Client UI. Data can be protected at field level, either by masking the content (replacing original characters with generic characters, such as asterisks) or by clearing or disabling the field.

Requirement

Here, we want to configure masking for Starting Balance and Ending Balance key figure fields in 2CIFIGLBALCUBE/2CCFITRIALBALANCE query result using Role-based authorization concept.

Product “UI data protection masking for SAP S/4HANA 2011” is used in this scenario to protect sensitive data at field level and must be installed in the S/4HANA system.

Let’s begin

Configuration to achieve masking for Starting Balance and Ending Balance key figure fields

Logical Attribute is a functional modelling of how any attribute such as Social Security Number, Bank Account Number, Amounts, Pricing information, Quantity etc. should behave with masking.

Configure Logical Attribute

Follow the given path:

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

Follow below mentioned steps:

Under “Maintain Logical Attributes”, maintain following logical attribute.

Starting Balance

Click on “New Entries” button

Enter “Logical Attribute” as “LA_STARTING_BALANCE”

Enter “Description” as “Starting Balance”

Select “Is Sensitive” checkbox

Click on “Save” button

Ending Balance

Click on “New Entries” button

Enter “Logical Attribute” as “LA_ENDING_BALANCE”

Enter “Description” as “Ending Balance”

Select “Is Sensitive” checkbox

Click on “Save” button

Maintain Analytics Technical Address

To mask the fields in Analytical Queries, Technical Information (InfoProvider-Query-InfoObject) is required. To retrieve the Technical Address for Analytical Query fields, you need to use Recording Tool feature to get the Technical Address as Technical Information on press of F1 key is not available here.

Refer to this blog to know how to use the Recording tool.

Follow the given path:

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

Follow below mentioned steps:

Under “Analytics Technical Address”, maintain technical address for following field.

Starting Balance

Click on “New Entries” button

Enter “InfoProvider” as “2CIFIGLBALCUBE”

Enter “Query” as “2CCFITRIALBALANCE”

Enter “InfoObject” as “ELTUIDCMP1”

Enter “Logical Attribute” as “LA_STARTING_BALANCE”

Enter “Description” as “Starting Balance”

Click on “Save” button

Ending Balance

Click on “New Entries” button

Enter “InfoProvider” as “2CIFIGLBALCUBE”

Enter “Query” as “2CCFITRIALBALANCE”

Enter “InfoObject” as “ELTUIDCMP4”

Enter “Logical Attribute” as “LA_ENDING_BALANCE”

Enter “Description” as “Ending Balance”

Click on “Save” button

Maintain Field Level Security and Masking Configuration

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

Follow the given path:

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

Follow below mentioned steps:

Starting Balance

Click on “New Entries” button

Enter “Sensitive Entity” as “LA_STARTING_BALANCE” and press “Enter” key. “Description” will get populated in corresponding fields

Check “Enable Configuration” checkbox

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

Ending Balance

Click on “New Entries” button

Enter “Sensitive Entity” as “LA_ENDING_BALANCE” and press “Enter” key. “Description” will get populated in corresponding fields

Check “Enable Configuration” checkbox

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

Masking in WD Grid (embedded) Query Display Mode

Follow below mentioned steps:

Execute “RSRT” T-Code

Enter “Query” as “2CIFIGLBALCUBE/2CCFITRIALBALANCE”

Select “Query Display” mode as “WD Grid (embedded)”

Click on “Execute” button

Enter highlighted search criteria in the corresponding fields and click on “Go” button

Starting Balance and Ending Balance field values will appear as masked

Note: For Starting Balance and Ending Balance Currency fields, original value will be replaced by 0.00 as the same is a Key figure and a notification will also be displayed by the system for the same.

Conclusion

In this blog post, we have learnt how Role-based masking is achieved in Analytical Queries in Query Monitor (RSRT T-Code) in WD Grid (Embedded) Query Display mode for masking sensitive Key Figure field information.
