Does anyone here know how to add an editable custom sublist for line items on a a custom record? I’m working on a custom record setup in NetSuite where I need an editable sublist on a parent record form. This sublist should allow direct line-item entry with custom columns, including an list/record > Source = '*Item' field* . Here’s the setup: • I have a parent-child relationship between the records, with a child record intended to act as the line items. • The parent record’s form includes a sublist where I want to manually add and edit lines, pulling in Inventory Item data (like Item, Description, Quantity on Hand, and Location). The problem: • NetSuite seems to only display this sublist as view-only, requiring a saved search, which blocks the ability to add new line items directly on the form. I’m looking for help to make this custom sublist editable so that users can add and modify line items directly. Any guidance on enabling this functionality would be appreciated!
