This page outlines how to force a Single-Page Invoice when the Debtor to Charge is different to the Debtor. By default, when the Debtor to Charge differs from the Debtor, the Invoice will be split onto 2-Pages, regardless of the Single Page Invoice settings within FBO One. This is hard-coded and therefore the changes must be made to the RDL Invoice/Receipt to override this.
download and open in Report Builder the invoice/receipt RDL template
add a calculated field to the InvoiceLine query, field that always returns TRUE
in case of invoices, the newly added calculated field will always return TRUE
in case of receipts, the newly added calculated field will always return FALSE because the InvoiceLine query is empty and contains no lines
The new calculated field will be replacing all instances of the existing IsSinglePageInvoice field (shown below in Cyan, are all the areas in which this field appears).
An RDL template example can be downloaded from here:
