Billing: Enhancement for reference and allocation numbers
Description
Financial accounting must recognize that certain billing documents belong to a business transaction. To this end, billing documents are given a reference number and/or an allocation number.
In Customizing for SD, you could previously set one of the following
numbers for the reference number and allocation number:
- A: Customer purchase order number
- B: Sales order number
- C: Delivery number
- D: External delivery number
- E: Current billing document number
If some of your customers do not assign an external delivery number, there is now an additional option:
- F: External delivery number if available, otherwise the delivery number
This new option is primarily required by automobile component suppliers.
Change system parameters in customizing
To do this, maintain the following fields in copying control for billing
documents (header):
- Reference number
- Allocation number
Further notes
Further information on setting the reference and allocation numbers can be
found in the Implementation Guide in the section 
"Maintain copying control for billing documents" .
