FSCM - Replication of ECC Customers as Business Partners

Hi All,

Can someone give a step-by-step guideline for a new implementation where we want to replicate all existing Customers in ECC-FI-AR FSCM Collections Management Business Partners.

I did follow a guide that I got, but, didn't achieve the result.

I have a problem that in the end of BP settings, when I select same number range for Customer Account Groups and Business Partner Account Groups (they are with same name and same number ranges), I get an error CVI_MAPPING039 and it doesn't let me save the settings.

Any help is highly appreciated as it is very urgent. I am stuck at this early stage and can not move any further.

Thanks,

Yash
