Dears,

Greetings!,

Hope you are doing well and safe,

Appreciate all your help and support by providing a great suggestions each day to many users,

Coming to my query, record.transform not allowing to create multiple invoices against a single sales order, even the invoice amount is less than sales order amount,

For Example, Sales order total amount = 100

Using record.transform created an invoice with total 10,

Still we have amount of 90 more to bill from sales order, but the sales order is already becomes pending billing after creation of first invoice which is having total amount of 10 and when we perform record.transform to create a another invoice with amount 20, it is throwing an error - invalid reference sales_order_id
