Using BPM (Blocks) when Incoming message has multilple rows

Question

Hi All,
I am using BPM in my scenario.I have a message with multiple rows coming.I want to check for a condition for each row of the incoming message.I am trying to use a block(Mode: For Each) and using a switch step inside this block.But in a block if u want to check for each line, we need to define a multiline container element as Source Interface message.Since I am already having multilple rows, I cannot give multiline option.Can someone give me some example scenarios where this type of scenarios are handled.
Thanks in Advance.

Hi,
Here I am picking a file with multiple rows
The Sender Message Type structure is
<ns:File_MT xmlns:ns="http://File/send">
  <recordset>
    <Slno />
    <Goods_Receipt_Date />
    <Material_Code />
    <Quantity />
    <Plant_Code />
    <Storage_loc />
    <Batch_Number />
    <PO_Number />
    <Item_Number />
    <Special_Stock_Indicator />
  </recordset>
</ns:File_MT>
Here the row recordset has multiple occurences.
For my BPM I have defined an Abstract Message Interface of similar structure.
1)I am using a receive step to receive the message.
2)I am using a transformation step for structure change.
3)Then I have to check a condition whether each of the fields, ie material number,plant code etc are null or not.
I am using a switch for that.In the switch I have 2 branches-for error records and correct records.
Now in the eror record branch, I want to append error records to a container using a container operation and finally send it to another system.
Since my Source message is already having multilple rows.ie 0...unbounded for recorset, I can't define a multiline for container operation.The container operation expects a multiline container element when using append statement.
How should I go about this?Should I define a Loop after the transformation step?
Can you give me any example scenarios where transformation steps are used to change a source message with mutilple rows are used?I referred the FlightBooking Example, http://sap.com/xi/XI/Demo/Agency-SplitMultiplebookingOrder but in that they are not using the MessageTypes which are already defined, in the mapping.
Can anyone help?
Thanks and Regards,
Soumya.
