I'm trying to create an advanced search for a custom field in the STANDARD BSP of the Opportunities. I need to visualize a pop up like the one for the product. I don't know which is the correct procedure to do this. I think that to realize an advanced search I have to create a new application layout linked to an application set, but how? In the search I need to display the list of possible value for the field and to have the ability of choose more than one value from the list (like for product) using the button CHOOSE.
I've already read the PCUI book but without result.
Do you have any suggestion? Which are the steps to create the application layout?
Thanks a lot,
