Filter lookups based on other selected lookups in model-driven apps are a useful feature. The purpose is to filter a lookup on a model-driven app form based on a previous lookup on the form which is already populated. Fortunately, achieving this doesn't require anything complex like custom JavaScript, making it accessible to a broad spectrum of users. Detailed guidance on configuring such filters can be found at this link.
Filter lookups in model-driven apps represent a crucial functionality in dynamic form population. This feature allows for the subsequent fields to rely on the value selected in a prior field, thus enabling a refined, user-specific data entry. The beauty of this system is in its simplicity, as it negates the need for complex JavaScript, and instead, opts for a more user-friendly approach, accessible to even those with rudimentary coding skills. Practical examples and comprehensive guidelines on its usage are available for further reading and exploration.
It is possible to filter a lookup on a model driven app form based on a previous lookup that has already been populated. This can be done without the need for custom JavaScript or any other complex solutions. This can be done by using the Dependent Option Set feature in Power Apps. This feature allows users to filter one lookup field based on the selection of another lookup field. This can be useful in situations where you need to filter a list of options based on the selection of another field.
For example, if a user has selected a country in a lookup field, then the Dependent Option Set feature can be used to filter a list of states in another lookup field based on the selection of the country. This can help to reduce the number of options that the user has to choose from, making it easier to select the correct option.
The feature can also be used to filter other types of fields such as date fields, currency fields, and text fields. For example, if a user has selected a certain date in a date field, then the Dependent Option Set feature can be used to filter a list of other dates in another date field based on the selection of the first date.
The Dependent Option Set feature is available in Power Apps and can help to make filtering lookups based on other selected lookups on model-driven apps easier and more efficient. This feature can also be used to filter other types of fields, making it a versatile and powerful tool for model-driven apps.
