Call Assembly in an Orchestration and use return code to delete dataset in Msgbox

Hi there.

I have to call an assembly right out of an orchestration. After the assemly is finished and everythings works fine, the datas (dataset) in the BTS 2009 MessageBox has to be deleted. For this I will not use a Send-Port, just a Receive-Port, because I will receive the datas for the assembly from a Flat File Adapter.

Now, I haven’t used orchestrations that much so I have some questions.

a) What do I have to do to call an assembly out of an orchestration?

b) At the moment I’m not sure how I can/have to handle the return code, that the dataset can be deleted from the MessageBox. Is this possible?

c) Anything else I have to take care of … like distinguished fields for that, means do I have to make all fields for the orchestration to distinguished fields, that the orchestration can put it thru to the assembly?

Perhaps you can give me some advice on this or some tips. Or you know an example for this.

Thank you very much in advance.

Best regards
