Discover the answers to some common questions about migrating Computer Aided Test Tool (CATT) test cases to extended Computer Aided Test Tool (eCATT) test scripts and leverage your existing investment in CATT.

Many companies that have invested heavily in building Computer Aided Test Tool (CATT) test cases and are now planning to upgrade to SAP ERP Central Component (ECC) have questions and concerns regarding their existing CATT development. In terms of compliance, it is important to have testing plans in place to assure the internal and external regulatory authorities that you are properly testing your processes and functionalities. I’ll answer three common questions related to CATT development.

Will CATT test cases, especially from R/3 Release 4.5 and below, be lost during the upgrade to ECC? Existing CATT test cases from an R/3 4.5 system or below are not lost during the upgrade and remain functional in ECC 6.0. How-ever, note that CATT test cases work for individual transactions only. extended Computer Aided Test Tool (eCATT) test scripts can test a business process across multiple SAP systems such as R/3, SAP Advanced Planning and Optimization (APO), SAP Customer Relationship Management (CRM), and more, as shown in Figure 1.
