Update Library step

Use the Update Library step to update a SharePoint library. You can, for example, use the Update Library step in a workflow to change the title or description of a library based on a decision or event.

To use the SharePoint steps in K2 Workflow Designer, you must have SharePoint installed in your environment. To see the version of SharePoint that K2 supports, view the Compatibility and Support Matrix.

Drag the Update Library step from the SharePoint category, Favorites bar, or the Recent category onto the canvas.
