Thanks for your response.
I newly learn biztalk because i need your helping so much. I think i did like you. I created two new messages in orchestration that have type of web type.
I creat a transform to map dataset (response from webservice) to biztalk schema. When I choose source schema, no message that I created appear, so I can’t map!!!
I think do I have to convert dataset type into biztalk schema before mapping?
