These FAQs serve as a first reference for questions about characteristic representations in the WM database and country-specific practices, e.g. in the settlement of company events.
A look at the FAQs can help to avoid inquiries via our Jira Service Desk. The FAQs provide new employees with basic knowledge and can be used for internal training purposes in your companies. In this way, we support you in optimizing processes, avoiding unnecessary efforts and thus saving costs.
The FAQs will be adjusted from time to time. We will inform you in a WM Customer Information issue as soon as a new FAQ version is available.
