Field help (INVCNDDAT)

This is the calculation start date for the invoicing open items.
This date is loaded with the order date. You can modify it but it must remain greater than or equal to the order date. In case of modification, a message suggests recalculating dates and periods related to the schedule lines. This recalculation does not apply to order lines that have already been invoiced, partially or completely.
 The display and management of this field (hidden, displayed, entered) are linked to the Invoicing term and depend on the field setup defined at entry transaction level.
