InterSystems IRIS BI (DeepSee) is a Business Intelligence (BI) technology that enables the real-time analysis of transactional data, and is designed to be optimal for embedding within transactional applications.
Often solutions with InterSystems IRIS BI can turn into a quite big solution with dozens of pivots and dashboards.
With every new IRIS BI solution release we can add changes that could influence the behavior of existing pivots or dashboards so they stop working. For example if we change the dimension or measure name, forget deploying some cubes or subject areas, conduct refactoring via mass renaming of cubes and its elements etc some widgets could stop functioning.
