Hello Jim,
TDMS exactly caters to your requirement. Example: If you chose to scramble vendor number then all the table-fields where the vendor number is used will be consistently scrambled across ERP. hence this will not effect your amount or any reporting calculations. TDMS offers standard content for material number, vendor number, name, address, customer number, name, address, personnel data. All these data are consistently scrambled.
You can also create your own scrambling rules based on your requirements.
Hope this answers your question.
Best Regards
Malthi
