Address& contacts can't be mapped automatically from prospect to customer

[Annzhii]

When creating a sales order from a quotation for a prospect, a customer is automatically created which is great, but if I have already created a customer by clicking the button on the prospect page, and then I convert the quotation to sales order, a new customer still will be automatically created.

I suppose the correct should fetch the existing customer:

I found that if I create a customer from a prospect, the field prospect_name will not be automatically filled.

So I filled the field prospect_name manually and it didn’t create a new customer.

It is possible to fill the field prospect_name automatically?

It will automatically fill when you create a quotation from the prospect opportunity and also make the sales order from the quotation, then create a new customer and link with the prospect. but for exising, you have to set it manually.
