One of the significant steps while implementing the Product Safety or any substance database related module in SAP EHS is understanding the data model. Data model defines how a company product is going to be represented in the SAP System. The different substance types and their inter-relationships defines the overall strategy. There are different data models available based on the company requirements like a standard data model consist of Real Sub linked to Pure Substances and Pure Substances are referenced / inheritance to pure substances. This is the data model which is used for even meeting the substance volume tracking and other functionalities. Example below shows the model

If you also have a DG into the overall company strategy the structure will differ with inclusion of Transport classification and Hazard Inducers information. The detail information about the different composition types and the way different components are mapped and their differentiation in to Polymers, monomer differentiation for Volume Tracking is another topic of importance to be checked while implementing the module. The strategy and direction depends on overall company direction and it should be properly analyzed before recommending a data model to an organization.
