Hi Karl
Our RTC2009R2 Addon Swissplaner 1.0 is available to Navision Customers and Partners Starting by the End of July 2012. Currently we are in RC2 state with 2 Customer-Projects. Any Tables from Navision can be used (service orders, Sales orders, production orders, items,BOM, to-dos...), we use an aggregation layer (jobs/tasks) and separate planning layers (planning runs, headers,elements, assignments). Ressources can be virtual or real and belong to multiple planninggroups. You can assign multiple timemodels and absences to resources and get capacity automatically calculated ...
We have also developed the RTC2009R2 Addon Swissworktime 2.0 with (barcode + Touchsupport) which is a an offline capable Timeregistration-application which is available also for XP/Vista/Win7 devices which will also be available for sharepoint-sites and mobile devices later this year.
The two Screenshots show our Planer (with Scheduler) which allows multiple assignments (Jobs-Task|Customer-Appointments-Tasks) to 4 Types of Resources (Persons, Machines, Workplaces and RentalItems) by dragdrop in grouped views. Grouping can also be done bei Status,Category,Flags)
If your interested in more information send me your company contact information to yamod#gmx°ch (replace #°)
