PII Scan with specific type of key columns

Products

• CA Test Data Manager (Data Finder / Grid Tools)

Issue/Introduction

Have came across a scenario where its seen that certain columns are not labelled as sensitive in some tables after PII scan even though the columns are added in classifiers used for PII scanning.

Details:

Individually all tables(A, B and C)  are classified as per the created classifier rule and tag.

However, with below combination of tables in the DataModel, the PII Scan doesn't assign the tag defined in classifier.

- C & A

But, for below combination of tables, PII Scan identifies the tag correctly.

- B & A

- B & C

Environment

TDM 4.10 and 4.11

Cause

Working as per current design.

Resolution

Due to the internal dependencies of the key columns and defaults settings of the PII scan implementation, for this use case to work, select "Scan Numeric Based Key columns" option during the PII scan.
