Inappropriate Calculation Descendant

Rule function

This rule tests whether certain elements in the calculation linkbase are descendants of a parent concept. The rule can specify the depth of the calculation tree that is processed. The rule is processed based on the following 3 pieces of data provided to the rule:

Errors should be returned for each instance where the defined element is a descendant of the parent element in the calculation linkbase, and not for every occurrence of the facts. For example, a single error will be returned if the calculation is incorrect (i.e., the element is a descendant of the parent element) and neither fact value is reported in the instance document.

Problem solved by the rule

This rule identifies where inappropriate calculation children have been included in the total of another element. An example of this is where the concept NetCashProvidedByUsedInContinuingOperations defined in the companies extension taxonomy includes the concept EffectOfExchangeRateOnCashAndCashEquivalentsContinuingOperations as a summation-child.

Example rule message
