You have a Customer Invoice which had multiple Sales Order References but when you preview the Customer Invoice only one Sales Order Reference is displaying in the Form Template.
Reproducing the Issue
- Go to Customer Invoicing work center.
- Select Invoice Documents view.
- Search and preview the Customer Invoice.
The field Sales Order Reference is a text field which is bound to $.CustomerInvoice.SalesOrderReference.ID and can accept only one value.
This feature is not available in the current release of SAP Business ByDesign.
The Sales Order Reference is being picked based on the selection while creating the Customer Invoice. The first or the last Sales Reference is taken and displaying in the Preview because, the field Sales Order Number is designed to display only one reference.
