Question about co settlement

Question

Hi ,all
I have a question below, can anyone give me some advise?
Prerequisite:
1. I want the field of CO/PP order of some P&L statement account is a
Req. Entry
2. When I execute the order settlement of ko88 (receiver is also a
order), I want a real-time fi document by primary cost element.
Symptom:
1. If I have the field status of the CO/PP order be a Req. Entry
in P&L statement account and execute ko88, system report Error message
F5808.
2. If I have the field status of the CO/PP order be a Opt. entry
in P&L statement, I can get a real-time Fi document, but line items of
the document haven’t the account assignment object (order).
Question:
How can I get the real-time FI document with the account which field of
CO/PP order is a Req. Entry. And the line item of the FI document can
automatically get the co object.
Eg.(FI document)
Dr: 1234567 100.00  (order)
  Cr: 1234567 100.00  (order)
best regards!

Answer 1

thank  you for your answer, I have solved the question,but now another problem occured.
when doing the consignment settlement,system gave the message:
Consignmnt settlement: No message was found for partner MM20/compny code 0001
Message no. M8443
Diagnosis
You are settling consignment or pipeline liabilities for vendor 0001 in company code MM20. For the information of the vendor, a document is created using the message determination function.
System Response
If no message record was found for a partner because of the message control settings, meaning that no output message can be created, no invoice  documents are created.
Procedure
In Customizing for Invoice Verification, check that the data for message determination has been maintained in such a way that an output message can be created for the vendors in the invoice document.
Execute function
If you want to settle without creating a document in message determination, you can switch off this message in Customizing.
thank you for your help!
