FI Journal Entry cannot be used with SD apps like Display Billing Documents.
In order to print FI documents, you can use the app Create Correspondence using the correspondence type SAP09.
This allows you to print the Journal Entry as an internal document, but it is not intended to be used for customer-facing communication.
To create and print customer-facing documents, please use the billing functionality of Sales.
For example you can create a debit memo request in order to create a billing document and to print it.
