Why wasn’t the Average Cost Price Calculated for Some Inventory Transactions or Sales?

This issue arises when the date of expenditure precedes the date of addition, causing the product to be expended at an average cost price (zero) if the first transaction for the product is an expenditure.

To resolve the issue, you need to adjust the addition date in the inventory transaction for the product or modify the date of the inbound requisition so that the inbound date precedes the outbound date.
