How to create complaints with reference to ECC Billing document (CRM 7.0)

Hi experts!

I use ECC 6.0 and CRM 7.0.

I have to create CRM complaints (ZCLR - CLRP) with reference to ecc billing documents.

I read the following topics and help:

1. How to create complaints with referenceto ECC Billing document

2. Re: How can we transfer billing documents from SAP ERP to CRM 2007?

3. http://help.sap.com/saphelp_crm70/helpdata/en/46/029ba32e675c1ae10000000a1553f6/frameset.htm

Made these settings:

1. Define the Business object type

Goto SPRO>CRM>Transaction>Settings for Complaints>Integration>Trnsaction Referencing>Define Object types for Transaction reference

2. Assign Business Object Types to Transaction Types

Goto SPRO>CRM>Transaction>Settings for Complaints>Integration>Trnsaction Referencing>Assign Business Object Types to Transaction Types

3. Implement a BADI - CRM_COPY_BADI_EXTERN.Check Implementation CRM_COPY_BADI_BILLDO for more information on the coding for referencing the ECC Billing document.

Goto SPRO>CRM>Transaction>Settings for Complaints>Integration>Trnsaction Referencing>BAdI: Create Complaint with Reference to External Transaction.

but still do not know,

1) if I should pre-replicate billing documents into CRM ?

2) Or, the system uses the RFC to find these documents in ECC to create reference?

Please help me.

Best regards Kostya.
