Concept of Inter-company Billing:
Inter-company business processing describes transactions which take place between two companies (company codes) belonging to one organization (Client / Company). The ordering company orders goods from a plant which is assigned to another company code. There could be several reasons for such transactions. For example:
Particular material is manufactured in particular plant only.
Economic Distribution cost from another plant, belonging to same group company.
& so on ......
Possible Inter-company Scenario's:
1. Inter-company Sales Processing:
A Sales Organization which is assigned to the ordering company code creates a sales order ordering goods from a plant assigned to another company code. The plant in the delivering company code delivers the goods to the customer for whom the sales organization placed the order. The Sales Organization receiving the order, Bills the ordering party and the delivering plant Bills the Company Code on behalf of which the material was delivered. The delivering plant billing the Company Code is Inter-company billing.
Customer A places an order to Sales Organization Z001, which belongs to Company Code Z001.
Sales Organization creates sales order with Delivering Plant as Z002, which belongs to Company Code Z002.
Plant Z002 delivers goods to Customer A.
Sales Organization Z001 bills the Customer A.
Plant Z002 bills Sales Organization Z001.
2. Inter-company Stock Transfer
A purchasing organization which is assigned to ordering company code creates a purchase order ordering goods from a plant to another company code. The plant in the delivering company code delivers the goods to the plant for which the purchasing organization ordered the goods. The delivering plant billing the Company Code of receiving plant is Inter-company billing.
Plant Z001 belongs to Company Code Z001. Plant Z001 raises a Purchase Order to Plant Z002 belonging to Company Code Z002 for requirement of say Material A.
Based on Purchase Order from Plant Z001, plant Z002 delivers Material A to Plant Z001.
Plant Z002 invoices Plant Z001.
Because the two companies balance their accounts independently, the delivering company must bill the ordering company for the goods.
Incoming invoice at Company Code Z001 in above scenario's can be posted manually or automatically, with an internal billing document via SAP EDI.
