I set the accounting processor to run every 1 minute. For invoice, journal,... everything is ok. However, I note that product cost wasn't updated automatically (we use average costing method). In the product cost - cost details tab, there is information on the invoice received, but the "product costs" tab, no information. If I run the "create product cost" manually, then the product cost is updated.
Can anynone tell me what's wrong. Thanks
