Picking Revenue from Item

Friends - Due to some challenges am not able to use Standard Line and Customer Site for Autoaccounting. And by using transaction type , it is limiting my combinations for Revenue account. So is there any SLA rule I can use to pick segments (Brand and Product) for Revenue account from Inventory ? Like if I know what the Item is and the corresponding brand and product is , can I load them in SLA ? I will appreciate any help. Or if there is anything I can do by adding product category for Revenue account derivation. Kindly
