You are looking for the Constrained by function. See the documentation here with an example: https://docs.mendix.com/refguide7/reference-selector#constrained-by
I created two separate entities where the System will have enumeration for an attribute type. This attribute should have stored enumerations (in which each value in the enumeration will pick up the specific sub-enumerated value based on selection).
How do I define the sub-enumerated values for the enumeration of the “System” attribute (Meaning: With an example System should be selected from ERP, MS package. System_Art will be filtered as a list based on the value of “System” selected)
At the domain model level, I would need some inputs.
