RE: Lookup for Product Family not all the Products
Hi, this is possible through the following:
Approach 1:
1. Create a new view in CRM which shows only Product Families.
2. On your form, open up the lookup field properties by double-clicking on the form, then scroll down in the Display Tab.
Set the Default View to the newly created system view, and turn off other views.
Approach 2:
If this does not seem to satisfy the criteria, then you may have to implement a lookup filter on form load using addFilter.
What it does is puts a filter on the lookup field to show only select set of records.
See the link here: https://msdn.microsoft.com/en-us/library/gg334266.aspx#BKMK_lookupControlMethods
But this approach requires some knowledge of form scripting using JavaScript.
Cheers!
