This is one of new feature going to be in October release of Business central.
On Sales transaction user need to select the line type such as Item, G/L Account ,Fixed asset etc. but sometime users says can we have default type as Item on every new sales orders rather than selection .
With upcoming business central version it is possible to set default line type as setup.
Go to Sales & receivables setup and select document Default line type as below
Select the desire value from dropdown list and go to sales order to create new transaction.
May be this small change will make difference for end users
Stay tuned for more features for upcoming versions.
