Transfrom process activity in JDeveloper

Question

hi
I am trying to map some Purchase Order data fetched from Oracle Applications E-Business
Suite to 850.xsd a definition supported by the EDI x12 business format.
If any body has tried out a similar exercise please help me how to desing the mapping using Transform Process Activity.
PFA the list of steps that I have followed.
1. I have selected an async process.
2.Created two Partner Links one to select data from Oracle Apps, by running a procedure and the other to choose the B2B docs deployed in the B2B server(850 definitions) in our case.
3.Used a Invoke and Reply process activity
4.Used a Assign activity to assign the variables of PO to the Transform Activity.
5.Now in the Transform I am trying to link say Po number to a particular segment of 850 that signifies PO number. But when I am trying to test and validate the transformation its givin error.
But to my utter surprise the BPEL process is getting complied and is also deployed successfuly on the BPEL server.Even the Audit trail from the UI of BPEL console shows the data being mapped to those required in 850.xsd
Is the process that I have followed is the correct method. Any suggestions will be of great help
Thanks and Regards

Hi,
Scope activity is being used as a container for other activities. Within the scope you can manage fault handling, compensation, variable declaration, correlation etc..
When you build, or design your process, you need to consider a use of a scope activity.
For example: You need to design a process that calls java class and a web service(or other 2 operations). You can:
1. Use 1 scope that contains both calls. That way, if you will have an error for either one of the services, you can catch it, and do something, like terminate the process.
2. Use 1 scope for each service call. That way, if you will have an error for either one of the services, you can catch it, and continue to the next process step (scope or other activity).
Also, within a scope you can declare an operation that Replay the scope. That way, if something happens -> begin the scope (and its activities) from the beginning.
There are many ways and purposes to use a scope. Again, it depends what is your requirement.
One important thing to consider –scope can influence on performance (just to be aware of).
