The reason for the task description is the item types in the transaction records.
If a sales order contains a service item/ non-inventory item, the saved search will display invoice records in fulfill/ receipt transaction join fields.
The reason is that service items in NetSuite are considered non-inventory items that require a fulfillment or receipt process. When a service item is added to a sales order in NetSuite, a fulfillment or receipt process is initiated to track the completion of the service. This process includes generating an invoice transaction that records the billing for the service. The invoice transaction is linked to the original sales order and can be accessed through the fulfill/receipt transaction join field in a saved search.
Therefore, if a sales order contains a service item, the saved search will display invoice records in the fulfill/receipt transaction join field, allowing the user to view the invoice transaction and other related transactions.
For each non-inventory or service item on the sales order, the saved search will show the invoice transaction in fulfill/ receipt transaction join field.
