Journal Entry For Services and Contracts

Hi All,

I have added new doctype for Services and Contracts and I want to create the JV Entry for Reference Type Services and Contract.
But Services and Contracts option is not available in Reference Type.

What If I customize the Reference Type Options and try to create JV Entry for Services and Contracts as reference type?

&

Is it right way to create JV Entry ?

I am asking because JV will affect GL Entries and General Ledger Report.

Party Type: Supplier and Party: Supplier Name

I can achieve same using Payment Entry also but there is no field to create reference link between Payment Entry and Services and Contracts.

Pls Suggest if there is any way to achieve so.
