Search path for control account

To determine the control account for an invoice transaction, LN searches for the most specific sales type or purchase type in this order:

1. The manually entered sales type or purchase type of the sales invoice header or purchase invoice header.
2. The sales type or purchase type of the sales order line or purchase order line. This can be an 'exception' defined for specific order details such as the item code, the item group, or the project.
3. The default sales type or purchase type defined for the business partner group of the invoice-to or invoice-from business partner.

For manual purchase orders and purchase schedules, if no purchase type is found in the purchase type exceptions, LN retrieves the default purchase type from the business partner group of the invoice-to business partner.

For internal invoices with bilateral invoicing or triangular invoicing, LN uses the default sales type or purchase type of the business partner group linked to the internal invoice-to or invoice-from business partner. For example, internal invoices can be generated for transfers, manual transfers, WIP transfers, and internal freight orders.
