The product line ties the service type to a set of general ledger accounts. It usually determines the accounts affected by the sale of contracts and by RMA issues and receipts. In Call Activity Recording, charge codes usually determine product lines. The system references product lines on the service type only if you do not set up charge and revenue product lines.

The system uses a service product line only if Use Item Prod Line in SSM Accounting Control is No. Otherwise, the system uses the item product line.

The product line lets you track and report on contract sales for different contract types. For example, to book the billing of annual contracts to a different GL account than semiannual contracts, you can create service product lines with different sales and sales discount accounts. You can then associate these product lines with different contract types.

When you post an invoice for a contract billing, the system credits the product line sales and sales discount accounts. You can modify accounts line-by-line on a contract if Modify Sales Accounts is Yes in SSM Accounting Control (36.9.10).
