No record found in the Item/version price per cost group table. Transfer a cost price for this item.

We are setting up a new company account. All the items are purchased, Item Type = Item. They are setup as Standard Cost. There is a Costing Version and all items have an Active cost price. They all have Site assigned. They all have a Cost Group assigned. But we get the error message below when trying to post Inventory journals.

No record found in the Item/version price per cost group table. Transfer a cost price for this item.

Any ideas on what we may have missed?

Figured it out. Found that InventItemCostGroupRollup table must be loaded along with InventItemPrice.
