We have configured one document type for the below mentioned object links
In configuration define object links there is a field called "Create Document". In that field we have defined as 2 i.e.Use transaction to create document that means we can directly go to CV01N transaction from the same screen
I am able to use this functionality i.e. calling the create document transaction screen in WBS Element -CJ20N.
Wanted to know how can i use the same functionality i.e.how to get that create document screen from sales document,Purchase Reqn & Purchase Order screens..
