Thanks for the hint with the app. However you are right with the SO and I would like to use the SO number also for the ProForma invoice. The question is now how to get it in the swx file (Report Designer) of the invoices. If I open my template for the most other status there is the number created by using [[ o.number ]]. When I put this at the end of the line with ProForma, the line disappears in the printout:

PRO-FORMA [[ o.number ]] [[ ((o.type == 'out_invoice' and o.state == 'proforma2') or removeParentNode('para')) and '' ]] [[ o.number ]]

in the sales order template another variable is used: [[ o.state not in ['draft','sent'] and removeParentNode('para') ]] Quotation N° [[ o.name ]] It does not work too / does not give me the required number i.e. "SO014". What can I do?

To summarize: You just want the SO number to be printed in the ProForma. like this "ProForma N° SOxxxx". 1_ When creating the SO it's first in a draft state 2_ Don't Confirm it, Just Save it, that is your ProForma ( or devis or Quotation). you can at this state send it by mail or print it; and it will be labeled "Quotation N°SOxxx". 3_ if you confirm it, it will be labeled "Sale Order N° SOxxx" (or Bon de Commande N° xxxx)

back from holiday I will test it soon and give a feedback ...

mhausle. Have you tested already?

Hello,sorry, no I did not test it because our tax accountant told me that taxes are to be due when the money arrives in our bank account, so for us no PRO FORMA invoice is necessary
