Medium-term sales and operations and medium to short-term production planning in the automotive
industry often employ cascading planning processes. One of the shortcomings of cascading
planning is the lack of coordination and feedback between different planning phases. Costly
problems in production due to unfeasible production programs and necessary troubleshooting are
often caused by unavailable resources or limited supplier capacities, because these restrictions of
subsequent levels weren´t discovered during the long-term planning. The establishment of a system
for the classification of planning restrictions and their originators is the main topic of this paper. In
addition, it will highlight the connection between single planning tasks and the correlation of
restrictions between different planning horizons. Finally, an experimental setup for implementation
approach for such a harmonized system will be presented.
