In the vendor portal, when selecting an item, it is necessary to populate the rate of that item from the item record. Additionally, upon clicking the ‘Setup Inventory’ button below the inventory detail field, a pop-up should appear. Within this pop-up window, all lots associated with the selected item and location should be listed below the ‘Serial/Lot Number’ field. Upon selecting a specific lot number, the Status and Available Lot Quantity for the chosen lot should be automatically populated. However, due to permission restrictions, it is not feasible to achieve this functionality using client-side scripting. Therefore, an alternative solution is needed to address this issue, particularly considering that the URL of the Suitelet page is an external URL and cannot perform the necessary searches.
