For VAT purposes we need to input a date of performance (date when the services ended) in the Invoices. This date does not flow from a sales order but needs to be entered at the line item level in the invoice.
We have the Billing Date (on the header level), Service.rendered date (on each line item of the billing document) and created on date( header) but these cannot be used as some of them are linked to pricing and others are at header level and flow from SD order.
is there a stand alone user defined date field that can be implemented
