Credit note created from history has same order number as the original sales order number

Hi All,

A business user created a sales order with six lines i.e. line#1 to 6 and processed 5 lines except line#2 till sales update.

Now , he entered a credit note for the above five lines but got the same order number generated as it was of the original sales order number.

He's unable to generate he invoice report now for this credit order.

Can the same order numbers (of both orig sales and credit orders) be an issue?

I am using JDE 9.1.  The invoice report has the following output in pdf

Original Invoice Details not found, kindly enter the Original Invoice Details in GST Additional application and then print Credit Note “
