Is it possible to have cascade TagInputs in SD dialog? Example: first TagInput (1T) will show BusinessPartner_Carriers and second TagInput (2T) shoud show Vehicles only from carriers in 1T. So 2T will have 1T list as input parameter for lookup. Is this construction possible?
Yes, it is possible. You need to assign the array field as a parameter, as you would expect. This feature is available since version 2015.11.
