Product Cost Price Field in Opportunity Product

Dear Support,

Is it possible to populate Standard Cost price field value to custom field in Opportunity Product?

We have a requirement of having Cost Price of the Opportunity Product, and we have created custom field in Opportunity product, however we are having difficulty getting the Product's Standard cost price to Opportunity Product. We have tried Workflow and we are not able to get the cost price via workflow.

We have read the following,  however not sure this will work in Dynamics CRM 2015 On-Premises

Is it possible to help us with JavaScript or any other way to achieve this?

Thanks
