Sap Sale Module: Re: [sap-log-sd] How to do billing without accounting/posting in ECC

There is much more than just routing the accounting entry to R3 or the
external system. Consider the following -
1. Where do you maintain the GL entries (not just the AR)? Billing
transfers revenues, costs (in some cases), discounts, rebates, etc. other
than just AR.
2. If AR is maintained in the external system and GL is in SAP, how would
you update GL in SAP?
3. You could permanently block posting to accounting based on whatever
criteria you want to use.
4. Rejection code will prevent the billing of the line item itself, not just
the posting of the accounting document. Further it will cause havoc with
your sales order processing history.
5. What event would trigger transfer of AR to external system? Batch or
realtime???
6. What is it that the external system does which cannot be handled by SAP?
I am sure you can add more to this list. I am not even attempting to
suggest a solution or approach. There is a lot more evaluation and analysis
that you need to do first.
Hint: a) Don't break the process (let the order to billing be intact). b)
Address the issue at the appropriate part - Transfer to Accounting c)
Ensure integrity between systems (Trigger for transfer & validations) d)
Ultimate integration of billing to FI.
Think through the whole process end to end.....

Thanks for elaborate suggestion.

Only concern is that we do not want any financial posting as that part of accounting is done in the external system. We are thinking of using the Rejection code for each line item instead. If a particular line item of the order need not be billed to AR then we will place a rejection code on it. Then we will run a new interface which will send all the line items which have a particular rejection code to the external system.

Let me know what do you think of this approach.
