I have a Master-Detail Relationship From an Object Flat to an Object Expense and also from Flat to an Object Housemate. Furthermore Expense and Housemate have a Many-To-Many Relationship through Junction Object ExpenseToHousemate.
----------Flat__c--------- -------| |--------- | | Expense__c---------ExpenseToHousemate__c------Housemate__c Flat__c(MD) Expense__c(MD) Flat__c(MD) Housemate__c(MD)
I want to create a Lookup Filter on the junction object, where I only show Housemates which are part of the same flat of which the expense belongs to. So far i cant reference the Flat__c Field on Expense from the junction Object, only the Flat__c field on housemate is available.
The Question is: Can i solve this with an Lookup Filter and how, or are there alternative ways, if possible without code since i strive to avoid code where its possible.
Thanks for Helping
