Hi Deepika,
I have checked what values are passing to it_service_i and input_fileds while creating from web ui, and maintained same values. Ref_guid as item guid (checked with object_guid as well), ref_kind as B (checked with A as well) and the field names. Tried by calling order maintain twice for service_i.
While uploading from excel, in debugging i can see same values what it is passing from web ui. But still those fileds are not updating.
Thanks & Regards,
Varma
