hi,
we have two custom modules (ModuleA and ModuleB) that are On2Many related. (MainCategory and SubCategory)
Products have Many2One relations to ModuleA and to ModuleB.
If a user edits a Product and selects a ModuleA (MainCategory) Record the other Dropdown for ModuleB (Subcategory) should only show Subcategories that have a relation to the previously selected ModuleA (MainCategory)
how can this be achieved?
