3753488 - "Error happened when invoking rule function: getAgeOfDependentInMonths, root cause: null" is encountered after introduction of Country/Region-Specific Dependent Configuration – 1H 2026

- A user has at least 1 dependent in their Dependents portlet.

- A business rule has been configured which uses the 'Get Age of Dependent in Months()' rule function, where a value is provided for the User ID parameter of the rule function. There is no value provided for the Country/Region parameter.

- It is mentioned in the Introducing Country/Region-Specific Dependent Configuration | SAP Help Portal What’s New Viewer, that for rules that retrieve dependent data "if User ID is provided (with or without Person ID) and the country/region field is empty, the system uses the user's country/region to determine the dependent's country/region”. However, the rule still fails to retrieve the country/region, thus causing the error, "Error executing rule XXX: ERROR_RULE_FUNCTION - Error happened when invoking rule function: getAgeOfDependentInMonths, root cause: null. Please check rule definition."
