Some Troubleshooting Steps

1. Ensure Page Items Are Correctly Mapped

Make sure :P22_AGE and :P22_ID are correctly defined on the page.

Confirm that P22_ID has a value when the button is pressed. If it's null, the UPDATE won't affect any rows.

2. Button Configuration

The button should have:

Action: Submit Page

Target: (Default)

Request: (Optional, but useful if you want to conditionally run the process)

3. Process Configuration

Your process should be:

Type: PL/SQL Code

Point: After Submit

Condition: Either "When Button Pressed" or "Always" (depending on your logic)

Process Success Message: Optional, but helps confirm it ran

4. Session State

Use Session State Viewer to confirm that P22_ID and P22_AGE have values before the process runs.
