In Inventory Transfer , there are way to add Inventory Adjustment Product one by one. TO add each product there is a lookup and that lookup provides all products mentioned in Inventory Transfer ( parent ) entity. But the issue was the product lookup >> advance lookup view which is not customizable.

The suggestion is to provide access to customize developer to add col. , filter col. , option for multiselect , sorting etc. to that specific view.

This view is a pcf control and developer don't have any control to customize.
