Use this window to enter and revise estimate versions. A version handles 
the business side of the estimate; quantities, costs, contingency and markups. A default 
version is always established when the estimate header is created. It is 
possible to create several versions to handle the quantity breaks and 
differentiated offerings to different customers. When a new version is created, 
all costs, insecurities and markups are copied from the previous version. Hence each version is unique 
which gives you the option to handle differentiated offering to different 
customers in a controlled way for the same work scope. 
This window is 
separated into two sections. In the upper section is a table in which you can 
create new versions and the lower are several tabs located in which the version 
specific data can be viewed or entered. For each version it is possible to set a 
valid from and a valid until date. These dates are just a recommendation of when 
in time a version should be considered as valid and whether it is still possible to perform 
calculations for the versions as well as creating deliverable lines.
For the description of each tab in the window, follow the appropriate link: Quantities, Currency Rates, Additional Cost, Markup,
