In the Purchase Order Management it is possible to send quotes directly with an email to your vendors from the requisition worksheet or the planning worksheet.
Here we are in the requisition worksheet and I just checkmarked the lines I want to make a quote on. Go to action, functions and handle journal and send mail. I say create quotes and OK. And should the lines be deleted after handling, yes they should. And the quote in an email with attached PDF is ready to send to my vendor. And if I go to the quotes, I can now see my new purchase quote that is also sent with mail.
