Mixed Loading Checks

Use

According to dangerous goods regulations, dangerous goods may not be transported in the same transport unit in just any combination, even if they individually meet regulations on quantity, packaging, and so on. An example of such a regulation-dependent mixed loading prohibition is listed here; in accordance with ADR, packages with the danger label 4.1 (inflammable solids) must not be loaded with packages with the danger label 1 (explosive substances and articles).

The dangerous goods check method Mixed Loading Checks within the Dangerous Goods Checks checks dangerous goods shipments to ensure that only such dangerous goods whose mixed loading is allowed in accordance with the dangerous goods regulations and their individual requirements are transported in the same transport unit.

Integration

The dangerous goods check method Mixed Loading Checks is delivered with the SAP component Dangerous Goods Checks (EHS-DGP-CHK).

Prerequisites

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

  • Specify Dangerous Goods Check Methods: You have specified the check method type 02 to indicated the check method Mixed Loading Checks as a header check method.

  • Specify Dangerous Goods Check Schemas: You have assigned the check method Mixed Loading Checks to a dangerous goods check schema.

    Note Note

    The initialization module DG63_CHK_INIT_HEADER must be before the check method Mixed Loading Checks in the dangerous goods check schema. For this, use the SProc (sequence processing) field in the activity Specify Dangerous Goods Check Schemas.

    End of the note.

  • The Customizing activities under Specify Settings for Mixed Loading Checks.

Features

The dangerous goods check method Mixed Loading Checks takes place on the following three levels, which are run 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 registered mixed loading prohibitions are recorded as error messages in the check log.

Segregation rules for enterprise-specific mixed loading groups

It is hereby possible for you to map individual, enterprise-specific stricter dangerous goods regulations.

You have the option of using the value assignment type Mixed Loading Check Details to assign real substances to enterprise-specific mixed loading groups. These enterprise-specific mixed loading groups can be any groupings or even individual substances, and do not depend on the regulations.

Example Example

For example, no shipments in which benzaldehyde is loaded with ethanol or other alcohols should leave your enterprise. This instance can be intercepted by the system with 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) must be loaded separately from the mixed loading group 2 (alcohols).

  • You use the value assignment type Mixed Loading Check Details to assign the real substance benzaldehyde to the enterprise-specific mixed loading group 1.

  • You use the value assignment type Mixed Loading Check Details to assign the real substance ethanol to the enterprise-specific mixed loading group 2.

End of the example.
Mixed Loading Rules

The mixed loading check Mixed Loading Rules is a check using regulation-dependent mixed loading groups such as acids, perchlorates, or powdered metals. These groups are assigned UN-listed substances.

You can use the value assignment type Dangerous Goods Regulations to assign UN-listed substances to both regulation-dependent mixed loading groups and mixed loading rules. Furthermore, you can use the value assignment type Mixed Loading Check Details to edit the value assignment Mixed Loading Group.

Example Example

For example, the IMDG Code specifies that barium permanganate (UN 1448, danger label 5.1) as an oxidizing substance is to be transported separately from powdered metals (such as magnesium powder, UN 1418). This instance can be intercepted by the system with the following settings:

  • In Customizing for Dangerous Goods Management, you define a mixed loading rule 1 for the IMDG code, which states: Separate from mixed loading group 15 (powdered metals).

  • For the UN-listed substance barium permanganate, you store the mixed loading rule 1 for the value assignment type Dangerous Goods Regulations

  • You use the value assignment type Dangerous Goods Regulations to assign the UN-listed substance magnesium powder to the mixed loading group 15.

End of the example.

Note Note

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

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

End of the note.
Segregation Rules for Segregation Keys

During this mixed loading check, the system bases the check on a regulation-dependent decision matrix.

You assign the segregation keys defined specifically for regulations in Customizing for Dangerous Goods Management to UN-listed substances.

Note Note

In the standard SAP system, the danger labels can be used as the segregation keys. If you have edited the characteristic Danger Label Number for the value assignment type Dangerous Goods Regulations, this information is used for the check method Mixed Loading Check. For this, you need to assign the segregation keys to the danger labels in the Customizing activity Specify Danger Labels.

However, the dangerous goods regulations also allow for special cases. For example, according to IMDG, bromine pentafluoride (UN 1745) is to be transported as dangerous label 5.1, but separately from 4.1 and 7. You can map such cases by making an additional entry under Segregation Key to override the Danger Label Number entry in the value assignment type Dangerous Goods Regulations.

End of the note.

You can also enter the characteristic Segregation Key for the value assignment type Dangerous Goods Regulations. In Customizing for Dangerous Goods Management, you have the option of specifying for a regulation whether the combination of two segregation keys is allowed and how the system is to react in this case.

Example Example

For example, the IMDG code specifies that class 3 substances (flammable liquids) must not be loaded with class 5.2 substances (organic peroxides). This instance can be intercepted by the system with 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 value assignment type Dangerous Goods Regulations.

End of the example.

Activities

For UN-listed substances and real substances, process the required assignments for the value assignment types Dangerous Goods Labels and Mixed Loading Check Details in accordance with the dangerous-goods-regulation-specific and enterprise-specific regulations.

Other Notes

  • The settings made are transferred to the dangerous goods master by the filling. However, you can also enter details relevant for the mixed loading check in the dangerous goods master directly. For this, you can use the Mixed Loading tab page.

  • The dangerous goods check method Mixed Loading Checks considers the loading of dangerous goods on separate shipping objects.

    Example Example

    For example, the joint shipment of two dangerous goods on the same tractor trailer may be prohibited. However, if one of the dangerous goods is on the loading area of the motor vehicle and the other is on the trailer, and the motor vehicle and trainer are mapped as separate shipping objects in the system, the transport may be allowed.

    End of the example.

  • Important: In the standard SAP delivery of the dangerous goods check method Mixed Loading Checks, combinations that are not entered in the Customizing tables under the Customizing activity Specify Settings for Mixed Loading Checks are considered to be permitted by the dangerous goods regulations.
