Oracle Cloud Item Transactions Without a Cost

Hello,

We are having trouble closing costing periods due to issues relating to item transaction costs being '0' and we are unable to figure out the cause. We have to fix them through "Manage Item Costs" for all items shown under "Pending Cost processing" by adding the cost of each item manually.

Is there a built-in report to show all items that are set up with a cost of ‘0’?

How would we be able to find out the cause of these items being transacted without a cost and prevent these errors?

Attached are some screenshots for reference.

Thanks in advance!
