Line item in sales order becoming twice

Hi Guys,

I am facing some issue in sales order in CRM. Issue is, I created sales order with two line items(10 and 20) in ECC and replicated it to CRM, when I open the same order in CRM, found that the second line item became duplicate(line items: 10, 20 20 in CRM order).

Could you please help me on this and do needful.

Thanks and Regards,
Venkat
