Question:

Is possible filter the product by productprogram in the form "Add opportunity product "?
If is not possible, can i change "product family" in "product program", but i don't know what i modify in a script for link to attributes.

Answer:

Add another combo box that is populated with the distinct product programs using the "PopulatePicklists" sub. Then add another filter in the "CheckForFilters" function which checks the product is in the program in the productprogram table.
