TDMS (Testing Data Migration Server) - Data Scrambling Made Easy
Many people may heard of TDMS as a tool for copy data from production system to testing system. However, they may not aware that one of the significant features in TDMS is that it can help to scramble or convert sensitive data before copy into to the testing system so that any important or sensitive information will not fall into wrong hands in case someone decided to steal the data from testing system and sell it to your company's competitors. In order to use this important feature, all you have to do is to define the import/export parameter, enter some simple abap coding and define which field name and data type to be scramble.
The demonstration in this document will show how simple it is to scramble the sensitive data with simple coding and little knowledge of abap with a few mouse click.

You just defined the scramble rules with domain type.
Since this rule is defined in domain type, TDMS will also scramble other tables with same field name and using the same data domain. Therefore, you don't have to worry that the sensitive data are missed for scrambling in case this fieldname's data may be updated in multiple tables.
