Data Source combine - Customer Invoice and Outbound Delivery Item Details

Hello,

I need create report where getting the outbound delivery item details ( like ship date, quantities, product, identified_stock)

and also need invoice number ( customer invoice number) which is available in the Customer Invoice Header or Detail source.

But try to create combined data source not able to join Customer Invoice and Outbound Delivery Item Details.

Since after adding any one of them as first datasource and try to add another data source from above then it doesn't shows up.

Anybody have idea how to get the invoice information (invoice number) and shipping data.

Thanks,

Viral.
