Notes, comments, descriptions and complaint fields hold names, card numbers and health details that column masking never sees. A masked CRM or core banking copy still leaks if its notes column is copied as it is.
Column masking treats a field as one kind of value, such as a name or an email. A notes field can hold any of them, in any order, so the values have to be found inside the text before they can be masked.
That is the point of masking values inside the text rather than blanking the field: the sentence stays, only the personal details change.
SAP long texts are covered, alongside CRM and case-management notes.
Documents and text use the same policies, the same engine and the same deployment as these results.
