class measures.business_rules.ME16(transaction=None)[source]¶

Integrating a measure with an additional code when an equivalent or overlapping measures without additional code already exists and vice-versa, should be forbidden.

Note :

Our understanding is that this should behave like ME32 with except checking for the inverse of the presence of the additional code.

This is based on our understanding of the intention and the poor wording of the business rule and the use of the word “should” are indicators that the language of this rule has not been through the same scrutiny as other similar rules.

Interpreted meaning:

Clashing measures :: Has a goods code in the same nomenclature hierarchy which references the same measure type, geo area, order number and reduction indicator and has no additional code, where one is defined on the validating measure or vice versa.

exception Violation(model: common.models.trackedmodel.TrackedModel, message: Optional[str] = None)¶

clashing_measures(measure) → measures.querysets.MeasuresQuerySet[source]¶

Returns all the measures that clash with the passed measure over its lifetime.

Two measures clash if all their fields listed in this business rule description are equal, their date ranges overlap, and one of their commodity codes is an ancestor or equal to the other.

static query_similar_measures(measure)[source]¶: Query measures where measure type, geo area, reduction, order number (or dead order number) match and additional code is null when the target measure has a populated additional code, or is not null when the target measure has a null additional code.

validate(measure)[source]¶

Perform business rule validation.

Raises: NotImplementedError – Must be overridden by subclasses

class measures.business_rules.ME17(transaction=None)[source]¶

If the additional code type has as application “non-Meursing” then the additional code must exist as a non-Meursing additional code.

UK tariff does not use meursing tables, so this is essentially saying that an additional code must exist.

This refers to the fact that the TARIC Measure record has separate additional_code_type and additional_code fields. Our data model combines these into a single foreign key relation to AdditionalCode.

It is not possible to violate this rule as a result.

class measures.business_rules.ME32(transaction=None)[source]¶

There may be no overlap in time with other measure occurrences with a goods code in the same nomenclature hierarchy which references the same measure type, geo area, order number, additional code and reduction indicator.

This rule is not applicable for Meursing additional codes.

exception Violation(model: common.models.trackedmodel.TrackedModel, message: Optional[str] = None)¶

This rule is not applicable for Meursing additional codes.

clashing_measures(measure) → measures.querysets.MeasuresQuerySet[source]¶

Returns all of the measures that clash with the passed measure over its lifetime.

Two measures clash if any of their fields listed in this business rule description are equal, their date ranges overlap, and one of their commodity codes is an ancestor or equal to the other.

compile_query(measure)[source]¶

Create a query that can be applied in a MeasureQuerySet.filter() expression to find Measure instances that match measure for the purpose of ME32 checking.

For instance, matching Measure`s will be of the same measure type, have the same geographical area and the same reduction. Matching measures will also be matched depending upon `measure’s order_number, dead order number and additional code.

The geographical area must exist.

exception Violation(model: common.models.trackedmodel.TrackedModel, message: Optional[str] = None)¶: The geographical area must exist.

class measures.business_rules.ME40(transaction=None)[source]¶

If the flag “duty expression” on measure type is “mandatory” then at least one measure component or measure condition component record must be specified. If the flag is set “not permitted” then no measure component or measure condition component must exist. Measure components and measure condition components are mutually exclusive. A measure can have either components or condition components (if the “duty expression” flag is “mandatory” or “optional”) but not both.

This describes the fact that measures of certain types MUST have components (duties) assigned to them, whereas others must not. Note the sub-clause also – if the value of the field “Component applicable” is set to 1 (mandatory) on a measure type, then when the measure is created, there must be either measure components or measure condition components assigned to the measure, but not both. CDS will generate errors if either of these conditions are not met.

exception Violation(model: common.models.trackedmodel.TrackedModel, message: Optional[str] = None)¶: The validity period of the goods code must span the validity period of the measure.

class measures.business_rules.ME87(transaction=None)[source]¶

The validity period of the measure (implicit or explicit) must reside within the effective validity period of its supporting regulation.

The effective validity period is the validity period of the regulation taking into account extensions and abrogation.

A regulation’s validity period is hugely complex in the EU’s world.

A regulation is initially assigned a start date. It may be assigned an end date as well at the point of creation but this is rare.
The EU then may choose to end date the regulation using its end date field – in this case provision must be made to end date all of the measures that would otherwise extend beyond the end of this regulation end date.
The EU may also choose to end date the measure (regulation?) via 2 other means which we are abandoning (abrogation and prorogation).
Only the measure validity end date and the regulation validity end date field will need to be compared in the UK Tariff. However, in terminating measures from the EU tariff to make way for UK equivalents, and to avoid data clashes such as ME32, we DO need to be aware of this multiplicity of end dates.

If no additional code is specified then the goods code is mandatory.

A measure can be assigned to:

a commodity code only (most measures)
a commodity code plus an additional code (e.g. trade remedies, pharma duties, routes of ingress)
an additional code only (only for Meursing codes, which will be removed in the UK tariff).

This means that a goods code is always mandatory in the UK tariff, however this business rule is still needed for historical EU measures.
