steps to reload order from ECC to CRM via request load

Hi Friends,

I created a sales order in ECC, the same is replicated to CRM, but got some error due to missing shipping conditions in CRM, so I downloaded the shipping conditions using initial load, now I want reload the orders from ECC to CRM, please let me know the steps to set-up request load in R3AR2 and which middleware object should be used to reload the orders from ECC to CRM.

Thanks and Regards,
Venkat
