SAP - Masking Sensible Data

Hi guys!!!

I have this scenario ERP DEV/QAS are copies from PRD (system copy/client copy), I want to know which SAP product or procedure I can implement in order to mask sensible data (ie. HCM tables) in non-production environment.

In DEV/QAS we don't want to show real data, for example, If in PRD a salary of a employee is 1 million, in DEV/QAS has to show 1 dollar

Regards
