Problem Description:
When a dependent line item used to filter a dropdown is deleted or has its format changed , Anaplan's underlying dependency link for the filtered dropdown can become stale. While the UI might show a newly created line item with the same list format as the dependency, the filter itself remains unapplied. This occurs silently without error messages, leading to an unfiltered dropdown despite correct-looking configuration. This behavior is inconsistent with other Anaplan features where dependencies are dynamically deduced and regularly refreshed without requiring manual user intervention.
Root Cause:
Anaplan's system automatically attempts to reassign dependencies when a new line item with the same list format is created after an original dependent item is removed or modified. However, this automatic reassignment does not fully reinitialize the underlying dependency link, leaving the dropdown filter ineffective.
Workaround:
To reliably restore the filtered dropdown functionality, users must manually force a full reinitialization of the dependency. This is achieved by:
- Opening the affected line item's format settings.
- Unchecking the "Dependent" option and confirming.
- Reopening the format settings, checking "Dependent" again, and confirming.
Impact:
This issue leads to confusion and unexpected behavior for users, potentially causing incorrect values to be selected or used if items that should be filtered out become visible. The disruption can lead to wrong configurations. The current workaround requires manual intervention, which can be time-consuming and difficult to diagnose without prior knowledge of this specific behavior.
Suggested Improvement:
- Anaplan could enhance its dependency management logic to automatically and fully refresh the underlying dependency link when a dependent line item is replaced or when a format change affecting dependency occurs.
- Anpalan could prevent the silent failure of dropdown filters and improve the reliability and user experience of dependent dropdown configurations.
