Field Masking – How to use Recording Tool for masking in Classical Reports


In this blog post, we will learn how to mask fields of S_ALR report “S_ALR87012082” which is a Classical Report in SAP GUI.

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:


Field Masking for SAP GUI” is a solution to protect sensitive data on SAP GUI screens at field level.Product “Field Masking for SAP GUI” is delivered to customer as add-on (UIM 100). To achieve Role-based masking, Add-on UIM 100 must be installed in customer system.


Role-based masking is required for S_ALR report “S_ALR87012082“. Some of the fields need to be masked on this report.

Recording Tool for Technical Address

In order to mask the fields on SAP GUI, Technical Information (Table Name-Field Name) is required which users can get by pressing “F1” on the field. There are some instances where “F1” is not working for some or all of the fields of S_ALR reports in SAP GUI. In our scenario, “F1” is not working for any of the fields on S_ALR report “S_ALR87012082“.

In this scenario “Recording Tool for Technical Address” will help user to find technical address for UI Masking. This report logs/records User Trace, Table Name-Field Name, Field Value and other metadata information that helps users to find Technical Address for masking.

Even after running the Recording Tool, if you do not see the Table Name-Field Name information of the field that you want to mask in the report then it is not possible to mask that field technically because of technical limitation.
