How to fill line item in complaint!!

Hi All,

I am creating a complaint doc using a follow up request through sales order.

Here what i am doing is internally calling a RFC FM to ECC and getting the sales order details

along with line item for creation but i see my line item is not being papulated for the complaint created.

I see the flow happening like some copy badi crm_copy_badi getting called and only orderadm_h method

is getting triggered and after which the FM to fetch sales order data and complaint is created.

Plz help me to papulate the line item data for the complaint created as a follow up doc.

Thanks..
