I have also tried the below code in changeset_end method, but I have no luck. I'm unable to populate sales order id to response header.
data: ls_header TYPE ihttpnvp.
ls_header-name = 'SalesOrderId' .
ls_header-value = ex_Order_id.
/iwbep/if_mgw_conv_srv_runtime~set_header( ls_header ).
I'm assuming because my system is on Sp4 for SAP_GWFND component. Is there a workaround?
