Quality Plan Form Not Working with RAISE FORM_TRIGGER_FAILURE

Hi All,

I have done below form personalization on 'Quality Plan' form to restrict Quantity Column should not be less than 100.

Seq: 1

Description: Validate Quantity

Level: Function
Enabled: Yes

Condition
---------
Event Trigger: WHEN-VALIDATE-RECORD
Trigger Object: Q_RES
Condition: :Q_RES.CHARACTER10< TO_NUMBER(100) AND :Q_RES_HEAD.NAME = 'PACKING ORDER LINES'

Processing Mode: Both

Actions
-------
Seq: 1 [Working]
Type: Message
Language: All
Enabled: Yes

Message Type: Error
Message Text: QUANTITY SHOULD BE GREATER THAN 100.

Seq: 2 [Not Working]
Type: Builtin
Language: All
Enabled: Yes

Builtin Type: RAISE FORM_TRIGGER_FAILURE

It is still getting save, although error message is working absolutely fine.
