Necessary steps for incorporating BPM collect pattern?

Question

I am working on my first BPM.
The scenario is as follows: Supplier information (CREMAS) has to be splitted into their respective receiver countries (This has been done with a switch) For each country all CREMAS has to be collected into one XML and sent.
I have decided on BPMCollectPatternTime.
What should I do in order to include a CollectPattern in my BPM?
What design objects should I copy to my namespace?
And how to configure receive, loop and transformation?

Hi Thomas,
So you are sending multiple CREMAS IDocs to SAP XI and you want a BPM to collect the IDocs together into separate XML messages by country.
In this case you dont need a switch statement, just use a time based collection routine and a correllation on the country field.
We have used this method extensively, you want to choose how to terminate the BPM. You can set up an infinite loop scenario with a time based termination via a deadline branch.
In order to use this in your own BPM create the Integration Process and add the following steps in the editor, this will aid you in understanding the various steps and how the process works.
You will need 3 Abstract Message Types:
1) Single IDoc Message Type
2) Multiline IDoc Message Type for Appended IDocs
3) Non Multiline IDoc Message type for the List of collected IDocs
First add a block step
  Mode = Default
  Local Correlation = Define Correlation on Country
Within the block step:
Deadline Branch = 1 minute for example
  Control step = Throw Exception
                      |
Main Branch = boldLoop Step Beginbold --- Receive Idoc Step --- Container Operation --- boldLoop Step Endbold
Loop Step
  Condition = (1 = 1)
Receive Step
  Message = Abstract Message Interface
  Use Correlation = Local Correlation
Container Operation
  Operation Append
Outside the block step:
Transformation Step
Send Step
Hope this helps,
