CAT
Customer Assemble Tool
...The .KTRs are written for integrating customer informations from several source system in one job. And the CAT would do this in three steps: 1. mapping in .KTR, which transfter the data only from one source system. 2. Define the priority matrix from all source systems for each target table and field. 3. CAT compile the .KTRs and the priority matrix into ESQL/C or java programs.
