quotation validity periods
Please give the solution for this issue.
I had raised a QT to my customer. He hadn't responded with in the
validity periods. So the QT had expired. But i don't want to loose
that customer. So here instead of raising a new QT against to him, i
want to change (extend) the validity periods of existing QT. Plz. let
me know whether it is possible or not. if yes how? if not why?
