In this Customizing activity, you create custom aggregation modes to enable Automatic Risk Analysis Aggregation.

In automatic risk aggregation, the software calculates an aggregated risk from multiple input risks. Any change in one of the input risks automatically updates this calculation. In this way, you can set up a hierarchy of risks, typically with different granularity, where the higher risks are automatically synchronized with changes happening on the lower levels.

Automatic aggregation only covers the analysis part of the risk. Analyses of the input risks are combined using defined calculation rules to generate an updated analysis of the aggregate risk.

The way in which the calculation of aggregate risks is performed depends on customizing settings. There are the following possibilities:

  • The standard (default) calculation mechanism provided by SAP
This mechanism can only aggregate corporate risks with a forecasting horizon based analysis into a target corporate risk. For each forecasting horizon the impact of the target analysis is calculated by combining all underlying analyses in one of the following ways:
  • Sum: the aggregated impact is the sum of all underlying impacts

  • Average: the aggregated impact is the average of all underlying impacts

  • Maximum: the aggregated impact is the highest of all underlying impacts

  • Minimum: the aggregated impact is the lowest of all underlying impacts

Similarly, the probability is calculated for each forecasting horizon by combining the underlying analyses in one of the following ways:
  • Sum: the aggregated probability is the sum of all underlying probabilities

  • Average: the aggregated probability is the average of all underlying probabilities

  • Maximum: the aggregated probability is the highest of all underlying probabilities

  • Minimum: the aggregated probability is the lowest of all underlying probabilities

  • Product: the aggregated probability is the product of all underlying probabilities (interpreted as fractions of 1)

  • A custom calculation mechanism implemented individually.
Such a custom logic requires the implementation of an ABAP class implementing the ABAP interface IF_GRRM_ANALYSIS_AGGREGATION. The standard logic, described above, is also implemented as such a class (CL_GRRM_ANA_AGGR_DEFAULT) and can be used as an example when implementing a custom logic.

To enable e-mail notifications to notify about failed aggregations or changes in underlying risks, you should complete the following customizing activities:

  • Users, who receive notifications are determined by the standard agent determination mechanism of GRC and the business event for this is 0RM_RISK_AGGREGATION. It can be customized in IMG activity Governance, Risk and Compliance → General Settings → Workflow → Maintain Custom Agent Determination Rules.
  • The notification messages are customized in IMG activity Governance, Risk and Compliance → General Settings → Workflow → Maintain Custom Notification Messages. Here, you use the message class 0RM_RISK_AGGREGATION and message numbers 01 (for aggregation failure notification) and 02 (for change update notification).

In this Customizing activity, you can define multiple aggregation modes. You define each mode in terms of the following parameters:

  • Cust. aggr
Identifying key
  • Imp aggr
Impact aggregation, mandatory for the default aggregation mode.
  • Prob aggr
Probability aggregation, mandatory for the default aggregation mode.
  • Reference to
The name of an ABAP class which implements a custom logic, mandatory for the custom aggregation mode.
If an ABAP class is in the Reference to field, the custom logic implemented in that class is applied. If the field is blank, the standard calculation is applied using the specified settings for impact and probability aggregation.
  • Customized aggregation
A descriptive name to appear on the user interface.
