3004546 - How to change the form title of the billing document output - SAP S/4HANA Cloud

You have a requirement to change the form title of the billing document output.

The form title is created via scripting in the form (can be found in Form.frmHiddenGlobalFields.txtPrintFormTitleText). Usually it's a concatenation of BillingDocumentTypeName and the document number. However, there is special logic, for example for cancellations and preliminary billing documents.
This KBA describes how to change the BillingDocumentTypeName, which in turn changes the form title.
