During Customer pickup a default verification details screen is displayed with a common field "Last 4 digits of Credit Card ". If an order is placed with a Gift Card and if entered with last four digits of Gift card and validation error is being thrown as "Enter last 4 digits of Credit card or choose different Validation Type".
Please suggest on how to enable it for Gift Cards.
The OOTB verification set up is not meant for gift cards.
The OOTB verification set up is not meant for gift cards. This has been set up for credit cards only. In case verification is required for gift cards as well a new verification criteria should be configured through the Channel Applications Manager, Configure Store Pick Up Administration> Configure Verification Criteria. This would then appear on the Customer Verification Screen. Custom implementation will have to be done for the logic behind this new criteria. For more details on this please refer the SCCS Implementation Guide, section: Customer Pick.
