Get ERP sales order in transaction history of a CRM service order

Hi,

We have a service order created in CRM, which gets replicated in ECC. Then a subsequent sales document is created in ECC.

Now we want to get this subsequent document in transaction history of the service order in CRM.

I have tried through configuration but I am not able to find any way to achieve this.

I am thinking of coding in CRM_DATAEXCHG_BADI, and creating a Docflow in the service order.

Please suggest a method to do this.

Thanks,

Nikhil Gupta
