3422939 - When Invoicing Multiple Invoice Requests At Once, Not All Invoice Requests are Brought Over Into the New Invoice Screen

You try to Invoice multiple Invoice Requests at once by selecting them in the Invoice Requests view. However, when doing so for a high number of documents, you notice that not all of the selected Invoice Requests are present in the New Invoice screen.

SAP Business ByDesign 

1. Go to the Customer Invoicing work center.
2. Open the Invoice Requests view. 
3. Select multiple 'To Be Invoiced' Invoice Requests
4. Click the 'Invoice' Button 

In the New Invoice Screen, you see that not all of the selected Invoice Requests appear. The same also happens when using the 'Invoice - Advanced' Button.

The functionality to Select multiple documents in the Invoice Requests screen will not work for more than 30 records at a time. This is due to how the system works internally with pagination, where the selection is restricted to all entries in the latest page, which is 30 records.

This is the expected system behavior. It is recommended to select and invoice at most 30 Invoice Requests at a time, until all records are processed.

Alternatively you can create an Invoice Run to invoice multiple Invoice Requests.
