Currently, Anaplan does not natively restrict number inputs to specific ranges. Users can input any numeric value, which may result in data integrity problems, especially in collaborative or decentralised planning environments. Introducing a validation capability—where model builders set upper and lower bounds for number line items—would allow immediate feedback to users attempting to enter invalid values. This could be implemented via a property in line item settings, where limits are defined, and the user interface prompts or blocks entries outside the specified range.
