Customers also work in a Kanban-oriented manner, inspired by the activity stacks. Here, the desire quickly arises for other users to be able to recognize whether other users are already in a data record and working there. Although we work with the “Assigned user” option in the documents here, there is the uncertainty that this can of course be forgotten before the user starts the actual processing of the document. Due to the invitations in Office products such as Excel, Word and PowerPoint, users naturally want to be able to see not only in an Excel sheet whether a colleague is already working in the same file, but also if the colleague is active in the same ERP data record. This would be an idea that arises from the current requirements with regard to joint processing and would be an incredibly unique selling point in the ERP sector.
