How to prevent multiple orders being submitted within a couple seconds?

LFS version: requires v12.09 or later

Context:

When an agent reaches the final Order Summary Screen in any of the Limio flows and clicks the Submit button, a callout is triggered to the Limio system to publish the order. After clicking Submit, the button becomes greyed out and unclickable to prevent multiple submissions.

However, a specific issue arises if the agent clicks Next after clicking Submit to navigate through the flow during order processing.

If the Next button is clicked:

1. The component on the Order Summary Screen reloads.

2. The Submit button becomes enabled again.

3. The ongoing order context is lost:

   • Agents cannot view the loading events of the ongoing order.

   • Agents might inadvertently click Submit again, submitting a duplicate order.

This behavior can lead to unnecessary issues, including duplicate submissions and associated consequences.

Solution: Introducing submittedOrderFlag

To address this problem, we introduced a new property called submittedOrderFlag in the flowOrderSummary component and an accompanying input for self-reference. Here’s how it works:

1. submittedOrderFlag: Tracks whether an order has already been submitted.

2. Self-Reference Input: Allows the flow to persist the submission status in the flow context.

Steps to Implement

1. Add Self-Reference to the Input:

   • Open the flow in the Flow Builder.

   • Locate the flowOrderSummary component.

   • Add the self-reference input to the component to check for an already submitted order.

2. Save a New Flow Copy:

   • After making the changes, save the flow with a new version.

3. Activate the Updated Flow:

   • Activate the new version to ensure it takes effect.

How It Works

• When an order is submitted, the submittedOrderFlag is set in the flow context.

• If the agent clicks Next and the component reloads, the flag prevents the Submit button from becoming clickable again.

• This ensures no duplicate orders can be submitted, even if the screen reloads.

Benefits

• Maintains order processing context.

• Prevents duplicate submissions and their associated issues.

By following these steps, you can effectively prevent duplicate order submissions in your Salesforce-Limio integration.
