I have managed to build a Custom-lookup-field with Mutliselection with the help of the Xrm.Utility.lookupObjects(lookupOptions)-function. Everythings work fine.
But I have to filter the views. I know, that I can add custom filters to my lookupOptions. But I have no idea how to create such a filter in XML.
Do anybody know a link where I can find informations about that?
The Filter should work like this:
The Lookupfield is on a case-form. With this lookup you can choose the product (customentity) which belongs to the case. But in this field you should only see the products of the customer. The products are linked to the customer.
