How can I pick a value from a list (PICK FROM) and use that value in a query (as a parameter)?
For instance: first from a picklist called 'Cities' I pick 'London'.
Then I run a query which shows me all customers in London.
The way I should do this is to create a process, use the BO Cities as process input.
Then in the process rule I want to use the query. (DISPLAY Customers)
There is my problem. How do I tell the query what parameter to use?
I do NOT want to use a BObject instead of a query, because then I cannot order and disable the attributes like I want them to be.
