What ‘s CATT(Computer Aided Test Tool)?How to deal with the CATT in the SAP System?什麼是CATT(電腦

SAP users use CATT frequently to upload master data or to make changes to master data records. SAP Consultants and Abapers tend to use it for creating test data. The transactions run without user interaction. You can check system messages and test database changes. All tests are logged. The CATT records your keystrokes while performing the actual transaction. You then identify the fields that you wish to change in that view. Then export this data to a spreadsheet to populate with the data required. This is uploaded and executed saving you keying in the data manually.

To perform CATT, it has to be enabled in your production environment (your systems administrator should be able to do this - SCC4). You will also need access to your development system to create the CATT script.

The process of uploading data with a CATT:

Activate CATT in your client
In transaction code SCC4 - click the change button
Double click on the client number
In the Restriction section, tick Allows CATT processes to be started.
