The third Webinar in the SAP Ecohub IFRS Webinar series focuses on dual accounting (IFRS and local GAAP), the processes and important milestones in SAP's IFRS implementation. You can register for the webinar  here and check out the blog from the speaker, Christiane Ohlgart, the Head of Subsidiary Accounting at SAP with responsibility for Accounting Policies and IFRS Group Accounting

I have recently spoken to a few SAP customers, who are in the process of implementing the new SAP GL and had many questions on configuration and parallel reporting with it. I strongly suggest attending this webinar or checking out its replay. I also found this guidance from SAP with a process map and documentation for parallel accounting that will be helpful.
