I am having choice field named "World Area" and i am having other lookup field named "Sales Region".I want to load only those Sales Region which belongs to selected World Area.
i have done lot of research but this seems impossible in Model Driven App, this functionality is very important and should be incorporated in near future.
I also have a similar requirement in my work, thus it would be great to have this ASAP.
Can’t you use the filter() function to create a collection of the subset you need and add it to a Gallery to do this?
This capability is possible if you create your Choice /Option Set as an entity and then relate the World Areas and Sales regions together. Then when adding you Lookup field you can filter the Lookup View to only show associated/related records. @PrasadY https://community.dynamics.com/crm/b/magnetismsolutionscrmblog/posts/how-to-filter-lookups-by-relate...
