I'm using the Create View task to create a view on a document library every time a process is initiaded, so that I can show only items on a list related to that process.

My problem is I can't choose the layout for this create view task - it allways creates a view based on the document library's "standard view" and even if I change the layout of the All Items view that does not alter the layout of the view created by the Create View task.

How can I define the layout to be used during the Create View task? Can I do it in skelta? Is there a way to change the default layout in a document library to be used when a new view is created?

In order to achieve your scenerio,There is a proper called Select columns under Default Settings.This property is used to select and add some columns from the available list once this is done click OK and update. You can refer Skelta Help files (Developer Guide) Using Skelta BPM.Net Activities -> Skelta Sharepoint activities -> Create view activity.

Cheers,
