The supply chain model is the basis for planning in SAP SCM. The system takes only master data that is assigned to a model into account in the planning. You can assign the master data to a model either in the Supply Chain Engineer or in the maintenance transaction for the master data in question. You can also assign products and location products to the model in the product master.

You can assign one or more planning versionsto a model. By creating different planning versions with different planning datasets, you can investigate all the aspects and options of a given supply chain situation and simulate the effects of different parameters. You can also create several models for simulation purposes.

All the master data released for the planning must be assigned to the active model and the active planning version (model 000 and planning version 000 respectively) in the production system. Master data transferred from SAP R/3 is automatically assigned to the active model and the active planning version.

You can create models and planning versions in planning version management (  Master Data Planning Version Management ) or in the Supply Chain Engineer.For more information, see Creating, Copying, and Deleting Model/Planning Version .

You can use the model consistency check to check the consistency of your supply chain model.
