Is it possible to have same Part number for Special order item , Drop Ship Item & Regular item

Are you wanting the items to be different so they default to Drop Ship, or Special Order when entered on the Sales Order? - If so, they would need to be different records, and also different item ids. Alternatively, you can create one item, and then on entry, users can specify whether the item requires special order or drop ship;

@Kumar - General rule in NetSuite when using Item numbers. It will allow you to use the same item number if the item types are different. (ex: Inventory Item, Assembly Item) therefore if they use the same item type you can't use the same item number when creating 2 or more distinct records. @suitedev is correct, a better approach is probably to just maintain 1 item, there is an option/link in orders to create either a dropship or special order type of transaction but if these items need to automatically generate Dropships or Special Orders , then you need to create separate items then just likely add a prefix or suffix to the item number to make it unique

Thanks a lot for the reply.
