Property Tree
Specifications ( PROD_COM , PURE_SUB , …) are characterized by data which are managed through property trees. These data are organized in classes which are themselves subdivided into characteristics.
For example: the “Flash point” class (chapter 9) consists of the following characteristics : Value, Pressure, Test type, Remarks…
There are several property trees which enable to put in light different information types (compositions, chemical properties, SDS,…). Information are actually the same, property trees are different ways to handle the same data.
Multi value / Multi Instances
Data origin
- Creation date;
- Person who created the data;
- Date when data was last changed;
- Person who last changed the data;
- Data origin:
- EH&S: data manually filled in or rule output modified*;
- ZEXP_XXX : rule;
- other: usually an uploading.
Remark
It is possible to modify the result of a rule while keeping the data origin of the rule ( allows to overwrite manually modified data next time the rule is launched).
It can be achieved by following this instruction: Utilities > Settings > Data provider + click on "Retain data origin/provider". This setting is temporary and only available until the next logoff.
Inheritance concept / Family of products
In SAP EHS, each PROD_COM generates its own SDS. It is possible to centrally managed data of homogeneous products within a “family”, by using master-slave inheritance link .
- Any SDS can inherent any section (1-16) from any other master SDS;
- Once inherited, it is linked. So any changes in the master cascade automatically to all slaves and will be implemented on next SDS validation => save time.
- For a master, there can be as many Slaves SDS as needed. It is also possible to link different templates on the same Slave, if templates do not cover the same sections.
It is possible to link any section of SDS (1 – 16), different templates exist. Recommended ones:
- Do not inherit composition and classification unless the products are exactly the same (different names for same product);
- Only inherit the section 14 directly from the DG_CL_SUB ;
- The standard templates for inheritance is SDS_FAMILY : all classes except the ones directly linked to the product's classification that are populated by the rules or manually maintained.
Finally, it is possible to create REAL_GROUP and use them as masters for some products with common hazards. For example, one mask for explosive products, one for environmental hazardous products, etc.
