Introduction
In this blog, we will learn how to mask Chart of Account field information based on G/L Account field information of Aging Analysis Smart Business app Analytical Query. Analytical Queries are used for reporting and analysis.
Chart of Account field information of Aging Analysis Smart Business app Analytical Query need to be masked where “G/L Account” is “0011230000”, “0013111000”, “0022010001”, “0022020001”, and “0024643000”. For other “G/L Account”, “Chart of Account” field will appear as unmasked.
Attribute based authorizations are dynamic determination mechanism which determines whether a user is authorized to access specific data sets which can be based on the context attributes of the user and data (for example, price of certain sensitive materials are masked).
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 Attribute Based Authorization Control (ABAC) concept.
Prerequisite
UI Data Protection Masking for SAP S/4HANA is a solution that allows you to protect restricted and sensitive data values at field level by masking, clearing, or disabling fields for those users who are not authorized to view or edit this data.
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 GUI, SAPUI5/SAP Fiori, CRM Web Client UI, and Web Dynpro ABAP.
Requirement
Here, we want to configure masking for Chart of Account field information based on G/L Account field information in Aging Analysis Smart Business app Analytical Query result using Attribute-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
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 Context 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.
G/L Account
- Click on “New Entries” button
- Enter “Logical Attribute” as “LA_EA_GL_ACCOUNT”
- Enter “Description” as “EA G/L Account”
- Click on “Save” button
Configure Sensitive 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.
- Chart of Account
- Click on “New Entries” button
- Enter “Logical Attribute” as “LA_EA_CHART_ACCOUNT”
- Enter “Description” as “EA Chart of Account”
- Select “Is Sensitive” checkbox
- Click on “Save” button
Maintain Analytics Technical Address
To suppress the records 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.
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.
G/L Account
- Click on “New Entries” button
- Enter “InfoProvider” as “2CIAPFLXBLAGING”
- Enter “Query” as “2CCAPFLXBLAGING”
- Enter “InfoObject” as “2CIAPFLXBLAGING-GLACCOUNT”
- Enter “Logical Attribute” as “LA_EA_GL_ACCOUNT”
- Enter “Description” as “EA G/L Account”
- Click on “Save” button
Chart of Account
- Click on “New Entries” button
- Enter “InfoProvider” as “2CIAPFLXBLAGING”
- Enter “Query” as “2CCAPFLXBLAGING”
- Enter “InfoObject” as “2CMBIWEI883S4US8477V0EERIY7”
- Enter “Logical Attribute” as “LA_EA_CHART_ACCOUNT”
- Enter “Description” as “EA Chart of Account”
- Click on “Save” button
Configure Value Range
Value Ranges are a set of pre-populated values which can be used to derive the context under which an action should be executed.
Follow the given path:
SPRO -> SAP NetWeaver -> UI Data Protection Masking for SAP S/4HANA -> Sensitive Attribute Configuration -> Maintain Metadata Configuration -> Maintain Attributes and Ranges for Policy -> List of Values Definition – Follow below mentioned steps:
Sensitive G/L Account List
- Click on “New Entries” button
- Enter “List of Values” as “VR_GL_ACCOUNT”
- Enter “Description” as “List of G/L Accounts”
- Click on “Save” button
Enter following entries in “VR_GL_ACCOUNT” Value Range
Follow below mentioned steps:
- Execute Transaction Code “/UISM/V_RANGE”
- Click on “VR_GL_ACCOUNT” Value Range
- Click on “Display<- -> Change” button
- Click on “Add New Entry” button
- Add following entries under “Include Value” tab and click on “Save” button
Policy Configuration
A Policy is a combination of rules and actions which are defined in one or more blocks. The actions are executed on a sensitive entity (field to be protected) which has to be assigned to a Policy. The conditions are based on contextual attributes which help derive the context.
Context Attributes are logical attributes which are used in designing the rules of a policy. They are mapped to fields which are used to derive the context under which an action is to be executed on a sensitive entity.
Sensitive Entities are logical attributes which are sensitive and need to be protected from unauthorized access.
Follow the given path:
SPRO -> SAP NetWeaver -> UI Data Protection Masking for SAP S/4HANA -> Sensitive Attribute Configuration -> Masking and Blocking Configuration -> Maintain Policy Details for Attribute based Authorizations – Follow below mentioned steps:
- Click on “New Entries” button
- Enter “Policy Name” as “POL_MASK_COA”
- Select “Type” as “Field Level Masking”
- Enter “Description” as “Mask Chart of Account based on G/L Account in EA Query”
- Click on “Save” button
Write following logic into Policy
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:
- Click on “New Entries” button
- Enter “Sensitive Entity” as “LA_EA_CHART_ACCOUNT” and press “Enter” key. “Description” will get populated in corresponding fields
- Check “Enable Configuration” checkbox
- Select “Attribute Based Authorization” option
- Enter “Policy Name” as “POL_MASK_COA”
- Click on “Save” button
Masking in WD Grid Query Display Mode
Follow below mentioned steps:
- Execute “RSRT” TCode
- Enter “Query” as “2CIAPFLXBLAGING/2CCAPFLXBLAGING”
- Select “Query Display” mode as “WD Grid”
- Click on “Execute” button
- Enter highlighted search criteria in the corresponding fields and click on “Go” button.
- Chart of Account Code and Description field value will appear as masked where “G/L Account” is “0011230000”, “0013111000”, “0022010001”, “0022020001”, and “0024643000”.
