Pax change enhancements for invoicing

Previous behavior:

·        A program is booked for 12 pax at €79.00 p.p.

·        An additional 2 pax were booked to the program item Lunch at €25.00 p.p.

·        The program item Lunch pax increases from 12 → 14 while the rest of the program remains at 12 pax.

·        Theprogram item Lunch is updated to 14 pax.

·        The total price of the program item Lunch is also update correctly.

·        The total price of the program is also updated correctly.

·        However,on the proforma, the program quantity remained as 12 pax. As the total price correctly increased, the program unit price did not. It changed from €79 →€83.17, which actually contradicts with the agreed confirmation and as a result cause for confusion.

New behavior:

·        For pax-dependent items: when the count  increases, we will now show these as separate lines on the proforma/ invoice.

·        For pax-dependent items: when the count decreases, a credit line is added to display the difference.

·        When adding an extra product, the product is automatically booked as aseparate item.

·        This way consistency is retained in booking on  program level and program level count and separate lines are used for increased or decreased counts on program item level.

·        If the pax is updated on program level, all items are updated accordingly, and no split lines are applied on the proforma/invoice.
