Yes, found
The data is in the table wpossa_woocommerce_order_itemmeta
On the example of an order
https://cabinet.b2bframes.com/admin/customorder/order/43111/edit/1) First, look for the product id order_item_id in the wpossa_woocommerce_order_items table:
SELECT * FROM `wpossa_woocommerce_order_items` WHERE `order_id` = 125594
- We need item with order_item_type=line_item
- get it order_item_id=104
2) Next, we are looking for fields in the wpossa_woocommerce_order_itemmeta table:
SELECT * FROM `wpossa_woocommerce_order_itemmeta` WHERE `order_item_id` = 104 ORDER BY `meta_id` DESC
- now we need to select the meta_key values that we will receive
- and take the value of the meta_value field, then you need to specify where to write it in the box
So, given that all this information is in the table with the goods, it is logical to write this in the goods fields.
