Questions Unit Cost entry for Non-Stock Item.

Hello Experts,

I have created a "Non-Stock Item" and the "Cost Based on" is defined as "Standard Cost". "The Current Cost" for this item is 20.00. I have created a sales invoice for this non-stock item and posted. I want to trace/see the corresponding cost entry (Unit Cost is 20.00) for this posted transaction. What is the default cost entry functionality for Non-Stock Items in Acumatica? How can be traced related entry? 

Appreciate yours earliest input on this.

Thanks for your time!

Best Regards,

Ranjith
