Common for unconditional and conditional column masking:
Column masking is not applied to Member Properties, Unknown and Calculated members, and Predefined time type hierarchy.
Caching not supported for masking.
Column masking not supported on PCH and advanced hierarchies.
Currently, column masking does not support the SQL interface.
Partial masking on numerical dimension field is not supported.
The original column data is preserved while masking because numeric data is masked with a number, and a date is masked with a date. You can specify a fixed pattern or a Regex expression for any string data type.
The masked value is displayed while browsing the semantic model on any BI tool with an MDX connection.
If using Tilde (~) for column masking and want to apply a filter on the masked value from Kyvos UI, then you must change the value of the field value separator as the default value of the kyvos.filter.value.separator property is also Tilde (~). Hence, you must change the default value of this property so that column masking with the Tilde character can function.
To apply column masking to a pre-defined hierarchy, you must select the full name of the hierarchy.
You can also create, delete, update, save, and assign column masking rules by using the Security Rest API's.
For conditional column masking:
The masking condition created using OR not supported.
Measure masking is not supported for the BI tools.
Measure masking condition on the field where display field also present is not supported.
Data conditions are only allowed on dimensions (level or attribute).
Conditional masking on date field is not supported.
Merging of measure values against fully masked only attribute or single level hierarchy is not supported.
Some of the filter condition on the dimension is not supported
