I am transferring my orders correctly from a different platform to the sma_suspended_bills and sma_suspended_items database tables. However, when I save my suspended orders and check the sma_costing table, I see that the purchase_id and purchase_item_id fields, as well as the cost fields, are coming as NULL. This affects my cost-profit calculation.

The only process I am performing via the integration is transferring data into the sma_suspended_bills and sma_suspended_items tables.

I am manually completing the sale from the POS screen. I open the suspended order, select the payment method, and then save it.

Where should I look to solve this problem?
