It is how you reproduce customer bugs on real payloads, load-test a release, and train end-users on data that looks like what they will see on Monday.</p> <p>Every copy is a compliance event. <strong>DSGVO, Art. 5</strong> requires personal data to be processed only for legitimate purposes and pseudonymised where practical. Most DACH enterprises have bought a deterministic masking tool — SAP TDMS, Delphix, Informatica TDM, IBM InfoSphere Optim — and wired it into the copy job. The tool rewrites classified columns: <code>KNA1-NAME1</code> becomes <code>Mustermann</code>, <code>BSEG-IBAN</code> becomes a fake IBAN that still passes checksum, <code>USR02-BNAME</code> becomes <code>USER042</code>. That covers the ~95% of PII that lives in schema-aware, row-level columns.</p>
