I got now a little workaround for my problem, which I wanna share with you guys.
I created now a SP 2013 WF where Im getting the datefield from an other list via the HTTP Webservice. After that Im going to start an SP 2010 WF with the datafield as an parameter
This SP 2010 WF is creating an Folder which is called: JourMix_[Date] and two subfolders which are called: Agenda_[Date] & Protokoll_[Date].
After that the Listitem from a list is used to create a new item in the Agendafolder and in an other list. The last step is deleting the old item
If you wanna have more details just ask them.
Maybe someone could use this.
SP 2013 WF:
SP 2010 WF:
But actually I would love to figure out how this is possible with one SharePoint 2013 Workflow. Has anybody an idea?
