Symptoms

Policy Builder is issuing a learning suggestion to set a specific maximum length for a parameter when that parameter already has that exact maximum length already configured.

Impact

Redundant learning suggestion is issued.

Conditions

-- Response learning is turned on -- Response parameter length is less than, but close to, the currently configured maximum length limit.

Workaround

You can either: -- Ignore the learning suggestion (Click the Ignore button). -- Turn off Learn from response.

Fix Information

Learning suggestion is no longer issued with already configured maximum parameter length value.
