    Hi,

    The following specification types are supplied with the standard system for the specification category Substance:

    • Real substance (REAL_SUB)

    A real substance is one that is physically present in a company.

    In the standard system, you can assign one or more materials to the real substance. You can assign values to the value assignment types of a real substance, or transfer values from listed substances using references or inheritance.

    • Real substance group (REAL_GRP)

    Real substance groups are used to represent families of real substances with the same properties.

    • Listed substance (LIST_SUB)

    A listed substance is a substance whose properties are described in laws and scientific literature.

    Unlike real substances, listed substances are not produced, traded, or used. You can use a listed substance as a "properties model" for a real substance by assigning the listed substance as the source specification in a reference or inheritance relationship.

    • Listed substance group

    Listed substance groups are used to represent families of listed substances with the same properties.

    • Copy template

    Copy templates contain predefined value assignments. You can use them to create new specifications for substances

      Hi Rajesh,

      I agree with Andreas. You have to decide the structure of the property tree first. Then for each and every branches of the property tree you should create classes/characteristics. Lets consider the example,

      A property tree called 'ZChemical1' and its used in specification type Z10 Hazardous chemicals. It requires 3 branches like

      ZChemical1

      ->Nitrogen content

      ->Chlorine content

      ->Iodine content

      We need to create these 3 branches as classes in the system with class type 100(substance). Also we need to create characteristics for the limits.

      Class: Nitrogen

      Characterisitcs1: Min value

      Characterisitcs2: Max value

      Characterisitcs3: Target value

      So you have to create these class/char's before itself and then you have to use the same in configuration(Specify value assignemnt types).

      Once you did value assignment, create a proprt tree and link the relevant value assignment.

      Finally link the property tree in specification type(Z10). So whenever you the specification type, system will pick up the relevant propert tree.

      Hope this clarifies, let me know if you need more clarification.

      WR,
