Hi Experts,

Usually from what I have seen CATT is not used for regular transactions in the productive environment. I have only seen LSMW used for the transfer of data from non-SAP systems to SAP systems. It guides you thru your data migration tasks.

- SAP advise not to use CATT in productive systems.

- Start of CATT processes allowed: This option determines whether you want to allow the CATT (Computer Aided Test Tool) process in the client or not. Computer Aided Test Tool (CATT) is tool provided by SAP to test different functionality of the SAP system. To run the CATT tool you can execute transaction SCAT. CATT process changes the database extensively and requires lot of system resources. So we recommend not to chose this option if you are in the production environment.

There has also been some comments on LSMW on this forum:

- The Legacy System Migration Workbench (LSMW) is a tool recommended by SAP that you can use to transfer data once only or periodically from legacy systems into an R/3 System.

My 2 cent would be why not develop a solution using Batch Input, BAPI etc?
