Mixed Loading Checks 

Use

Dangerous goods laws state that dangerous goods may not be transported together in any combination in the same transport unit – even if they fulfill the regulations individually with regard to their quantity, packaging, and so on. As an example for a regulation-dependent mixed loading prohibition of this type, it is stated that according to ADR, packages with the danger label 4.1 (flammable solids) must not be loaded together with packages with the danger label 1 (explosive substances and articles), for example.

The dangerous goods check method mixed loading checks within dangerous goods checks checks dangerous goods shipments to make sure that only those dangerous goods are transported on the same transport unit that are permitted for mixed loading in accordance with the dangerous goods regulations and their individual requirements.

Integration

The dangerous goods check method mixed loading checks is delivered with the SAP component dangerous goods checks (EHS-DGP-CHK).

Prerequisites

You have edited the following IMG activities in Customizing for Dangerous Goods Management:

·        Specify Dangerous Goods Check Methods: You have set the check method mixed loading checks as a header check method by assigning it the check method type 02.

·        Specify Dangerous Goods Check Schemas: You have assigned the check method mixed loading checks to a dangerous goods check schema.

The initialization module DG63_CHK_INIT_HEADER must come before the mixed loading checks check method in the dangerous goods check schema. To do this, use the SProc field in the IMG activity Specify Dangerous Goods Check Schemas.

·        The IMG activities under Specify Settings for Mixed Loading Checks

Features

The dangerous goods check method mixed loading checks is run at the following three levels, one after the other in sequence.

...

...

       1.      Segregation rules for enterprise-specific mixed loading groups

       2.      Mixed loading rules

       3.      Segregation rules for segregation keys

Even if the system registers mixed loading prohibitions at the first and most detailed level, all levels are still processed. The mixed loading prohibitions registered are noted as error messages in the check log.

Segregation Rules for Enterprise-Specific Mixed Loading Groups

You can use this function to map individual enterprise-specific special cases and tighter restrictions than are covered in dangerous goods regulations.

You can assign real substances to enterprise-specific mixed loading groups using the Mixed loading check details value assignment type. These enterprise-specific mixed loading groups can be any groupings or even individual substances, and are not dependent on regulations.

For example, no shipments are to leave your company in which benzaldehyde is loaded together with ethanol or other alcohols. This case can be caught by the system if you make the following settings:

·         In Customizing for Dangerous Goods Management you define a segregation rule for enterprise-specific mixed loading groups, which states that the mixed loading group 1(benzaldehyde) is to be loaded separated from the mixed loading group 2 (alcohols).

·         You assign the real substance benzaldehyde to the enterprise-specific mixed loading group 1 using the Mixed loading check details value assignment type.

·         You assign the real substance ethanol to the enterprise-specific mixed loading group 2 using the Mixed loading check details value assignment type.

Mixed Loading Rules

The mixed loading check mixed loading rules is a check for regulation-dependent mixed loading groups such as acids, perchlorates, or powdered metals. UN-listed substances are assigned to these groups.

You can assign both regulation-dependent mixed loading groups and mixed loading rules to UN-listed substances using the Dangerous goods regulations value assignment type. You can also edit the Mixed loading group characteristic in the Mixed loading check details value assignment type.

The IMDG Code, for example, specifies that barium permanganate (UN 1448, danger label 5.1) is to be transported as an oxidizing substance separated from powdered metals (such as magnesium powder, UN 1418). This case can be caught by the system if you make the following settings:

·         In Customizing for Dangerous Goods Management you define a mixed loading rule 1 for the IMDG Code that states: Separated from mixed loading group 15 (powdered metals).

·         For the UN-listed substance barium permanganate you store the mixed loading rule 1 under the Dangerous goods regulations value assignment type.

·         You assign the UN-listed substance magnesium powder to the mixed loading group 15 in the Dangerous goods regulations value assignment type.

No UN-listed substances exist for foodstuffs. To be able to map in the system the restriction Away from foods required in some regulations, it is possible to also assign real substances that are not dangerous goods (for example, honey) to a mixed loading group.

Important: For the dangerous goods checks to run, in the above case it is necessary to create dangerous goods master records for the material honey.

Segregation Rules for Segregation Keys

In this mixed loading check, the system checks on the basis of a regulation-dependent decision matrix.

You assign the regulation-dependent segregation keys you specified in Customizing for Dangerous Goods Management to UN-listed substances.

In the standard SAP system the danger labels are supplied as segregation keys. If you have entered a value for the Danger label number characteristic in the Dangerous goods regulations value assignment type, this information is used for the Mixed loading check check method. For this you must assign the segregation keys to the danger labels in the IMG activity Specify Danger Labels.

The dangerous goods regulations also cover special cases. For example, bromine pentafluoride (UN 1745) is to be transported as danger label 5.1 according to the IMDG Code, but separated from 4.1 and 7. You can map this type of case by overriding the entry under Danger label number in the Dangerous goods regulations value assignment type by making an additional entry under Segregation key.

You can also enter a value assignment for the Segregation key characteristic under the Dangerous goods regulations value assignment type. In Customizing for Dangerous Goods Management you can specify for a specific regulation whether the combination of two segregation keys is permitted and how the system is to respond in each case.  

The IMDG Code, for example, specifies that class 3 substances (flammable liquids) must not be loaded together with class 5.2 substances (organic peroxides). This case can be caught by the system if you make the following settings:

·         In Customizing for Dangerous Goods Management you define a segregation rule that states that the segregation key 3 must be transported separately from segregation key 5.2.

·         You assign the corresponding danger labels or segregation keys to UN-listed substances in the Dangerous goods regulations value assignment type.

Activities

For UN-listed substances and real substances, edit the required assignments in accordance with dangerous goods regulations and enterprise-specific rules under the value assignment types Dangerous goods regulations and Mixed loading check details.

Other Notes

·        The settings made are transferred by filling to the dangerous goods master. If you wish, you can also enter information relevant for mixed loading checks directly in the dangerous goods master. For this purpose the Mixed Loading tab page is available.

·        The dangerous goods check method mixed loading checks takes the loading of dangerous goods in separate shipping units into account.

For example, the common transport of two different dangerous goods on the same tractor trailer can be prohibited. If, however, one of the dangerous goods is loaded on the main load area of the tractor (truck) and the other on the trailer, and if tractor and trailer are mapped as separate shipping units in the system, transportation can be permitted.

·        Important: In the SAP standard system for the dangerous goods check method mixed loading checks, combinations that are not entered in the Customizing tables under the IMG activity Specify Settings for Mixed Loading Checks are considered as being permitted with regard to dangerous goods regulations.
