This article explains the functionalities, benefits, and steps involved in utilizing CATT for data manipulation within the SAP environment.

Define CATT

CATT, short for Computer-Aided Test Tool, is a powerful utility within the realm of SAP Basis that plays a pivotal role in streamlining testing and data manipulation processes. SAP Basis, often referred to as the technical foundation of SAP systems, encompasses various components that manage the underlying infrastructure, configuration, and administration of SAP applications. CATT is a tool that falls within the domain of SAP Basis and offers significant benefits for testing and data-related tasks.

Key Features of CATT

  • Data Manipulation: CATT allows users to record their interactions with SAP transactions and then replay those interactions automatically. This is particularly useful for tasks such as uploading data, modifying master data records, or testing changes in a controlled environment.
  • Automation: With CATT, tasks that require repetitive manual intervention can be automated, reducing human errors and saving time. This is especially beneficial for tasks involving large datasets or frequent updates.
  • Testing: CATT provides a controlled environment for testing changes before they are implemented in a production setting. Users can execute recorded scripts and verify that desired outcomes are achieved without affecting live data.
  • Data Integrity: By automating data manipulation tasks, CATT helps maintain data consistency and integrity. This is crucial for ensuring accurate reporting, compliance, and reliable decision-making.

Step-by-Step Guide to Using CATT

  1. Activate CATT: Open the transaction code SCC4, change the client settings, and enable CATT processes to be started.

  2. Upload Data using CATT:

    • Access the transaction SCAT.
    • Define an import variant for the fields that require modification.
    • Create a text file with the required data for modification, following the specified format.
    • Configure the recorded entry fields in the CATT, mapping them to the imported text file data.
  3. Executing Modifications:

    • Execute the test case within CATT.
    • Choose the external text file containing the data.
    • CATT will process the recorded actions, updating the specified data fields accordingly.


SAP's Computer-Aided Test Tool, or CATT, exemplifies the synergy of automation and data management within the SAP ecosystem. From its origins as a testing tool, CATT has evolved to be an indispensable asset for SAP users, enabling them to automate data uploads and modifications with precision.
