change unit price to 5 decimal places

Dear Experts,

We have one type of inventory that has selling unit price with 5 decimal places. Is there as way to set specific inventory to display unit price with 5 decimal places or do I have to change the unit price for entire SAP?

Earlier I tired to change the unit price to 5 decimal places by going Administration > System Initialization > General Settings > Display and tried to change the “Price” field from 2 to 5 but the system gave me an error message that it can not updated while another user connected to the company even though I was the only user logged in to the SAP. Do you have any suggestion, how can I fix this issue? Currently, I am running SAP B1 8.80 pl 17.

Thanks.
