Set Base Price Origin to Item Cost but some invoices still show as Last Purchase Price

Hi All,

I am using SAP B1 v9 PL5.

At Administration > System Initialization > Document Settings, I have set the Base Price Origin to "Item Cost"

However when I sometimes when I created an invoice, and click on the Gross Profit button, I see that it's set to "Last Purchase Price".

By right it should be set to "Item Cost".

Has anyone encountered such an issue before?

Thanks!

Ivan
