Processing Several Records in a CSV File

Question

Hello Experts!
I'm currently using XI to process an incoming CSV file containing Accounts Payable information.  The data from the CSV file is used to call a BAPI in the ECC (BAPI_ACC_DOCUMENT_POST).  Return messages are written to text file.  I'm also using BPM.  So far, I've been able to get everything to work - financial documents are successfully created in the ECC   I also receive the success message in my return text file.
I am, however, having one small problem...  No matter how many records are in the CSV file, XI only processes the very first record.  So my question is this: Why isn't XI processing all the records?  Do I need a loop in my BPM?  Are there occurrence settings that I'm missing?  I kinda figured XI would simply process each record in the file.
Also, are there some good examples out there that show me how this is done?
Thanks a lot, I more than appreciate any help!

Matthew,
First let me explain the BPM Steps,
Recv--->Transformation1->For-Each Block->Transformation2->Synch Call->Container(To append the response from BAPI)->Transformation3--->Send
Transformation3 and Send must be outside Block.
Transformation1
Here, the source and target must be same. I think you must be know to split the messages, if not  see the below example
Source
<MT_Input>
<Records>
<Field1>Value1</Field1>
<Field2>Value1</Field2>
</Records>
<Records>
<Field1>Value2</Field1>
<Field2>Value2</Field2>
</Records>
<Records>
<Field1>Value3</Field1>
<Field3>Value3</Field3>
</Records>
</MT_Input>
Now , I need to split the messages for each Records, so what I can do?
In Message Mapping, choose the source and target as same and in the Messages tab, choose the target occurrence as 0..Unbounded.
Now,if you come to Mapping tab, you can see Messages tag added to your structure, and also you can see <MT_Input> occurrence will be changed to 0..unbounded.
Here is the logic now
Map Records to MT_INPUT
Constant(empty) to Records
Map rest of the fields directly. Now your o/p looks like
<Messages>
<Message1>
<MT_Input>
<Records>
<Field1>Value1</Field1>
<Field2>Value1</Field2>
</Records>
</MT_Input>
<MT_Input>
<Records>
<Field1>Value2</Field1>
<Field2>Value2</Field2>
</Records>
</MT_Input>
<MT_Input>
<Records>
<Field1>Value3</Field1>
<Field3>Value3</Field3>
</Records>
</MT_Input>
</Message1>
</Messages>
