Magento 2 Reorder functionality missing for migrated orders

Question

We have migrated customers and orders data from M1 (1.14.3.1 EE) to M2 (2.3.1 commerce) successfully But when we are doing testing at the admin end for the orders found that the Reorder button was missing. Then we checked below scenarios

1. Reorder settings enabled (System -> Configuration -> Sales -> Sales -> Reorder)

2. Crated an order in the frontend then it is showing reorder at admin end.

Can anyone have faced this kind of issue could you please advise.

Answer 1

Have not seen this before in stores that we have migrated so far. But perhaps you could follow the steps Magento 2.3 takes to determine if an order can be reordered or not.

1. The logged in user needs to have permission to use the reorder function. (I assume this is the case since you can reorder other orders). - Magento\Sales\Block\Adminhtml\Order\View::_isAllowedAction('Magento_Sales::reorder')
2. The Reorder setting needs to be enabled for the right store view. Were the orders assigned to the correct store view during migration? - Magento\Sales\Helper\Reorder::isAllowed
3. The order cannot be in "hold" or "payment review" status. - Magento\Sales\Model\Order::_canReorder()
4. The order cannot have the reorder flag set to false. This is not something the core would do, but a module might. - Magento\Sales\Model\Order::_canReorder()
5. All ordered products in this order must exist in the store. This is perhaps the most important condition, and a most likely cause. Check if your imported orders have the correct product_ids linked in the sales_order_item table. And that these products exist. - Magento\Sales\Model\Order::_canReorder()
