Can you help? My Invoice transaction Journals are not showing an amount under COS, even though each product has a cost entered & its under the right account asset. ??

Yes, I have realised that the initial cost was not entered when the stock items were first created on the Inventory. When I go back to transaction details I can see it can now be entered here, however, do you know what stock adjustment account I should select when the stock asset account shows “stock asset" and my products are automatically listed as "retained profit balance forward account" as the stock adjustment account?
