Maintaining Objects in Model
An important aspect of supply chain modeling is to maintain individual objects in the model. However, to simplify maintenance, you can also maintain all the object types in one step. In this step, you can simultaneously add or delete objects to or from a model.
Maintain the master data for the individual objects.
