*** Updates for 2016 Included ***
Greetings All,
Like an old friend, Daylight Savings Time affects us in most parts of the world at least twice per year. Depending on your hemisphere, you may be springing forward or falling back, but either way you need to ensure your awareness and any proactive follow up in your SAP environment.
- Is your SAP environment prepared for Daylight Savings Time and any potential effects?
This document will help you begin to answer that question and point you to the relevant SCN Posts / SAP Notes / SAP KBA's and documentation for potentially affected components to fuel your quest for minimal problem or disruption due to Daylight Savings Time. This posting will evolve over time and is one we will add to every year as new information on this topic comes to the forefront. This document will not replace the incident solving process if you have specific questions on a particular component area. Feel free to raise some general Q&A on the topic within SAP Community Network but if your request requires a more specific feedback to address we request you open an incident to the appropriate SAP component so we can action.
