Very simple, but not working Table to Flat File

Question

I'm new to ODI, but I am having too much difficulty in performing a very basic task. I have data in a table and I want to load the data to a flat file. I've been all over this board, all over the documentation, and all over the Googles, and I can not get this to work. Here is a run down of what I have done thus far:
1. created a physical schema under FILE_GENERIC that points to my target directory
2. created a logical schema that points to my new physical schema
3. imported a test file as a model (very simple, two string columns, 50 chars each)
4. set my parameters for my file (named columns, delimited, filename resource name, etc.)
5. created a new interface
6. dragged my new file model as the target
7. dragged my source table as well
8. mapped a couple of columns
9. had to select two KMs: LKM - SQL to SQL (for the source) & IKM - SQL to File Append (for the target)
10. execute
Now, here is where I started hitting problems. This failed in the "load data" step with the following error:
+7000 : null : java.sql.SQLException: Column not found: C1_ERRCODE+
I found a note on the forum saying to change the "Staging Area Different From Target" setting on the Definition tab. Did that and selected the source table's schema in the dropdown, ran again. Second error:
+942 : 42000 : java.sql.SQLException: ORA-00942: table or view does not exist+
This occurred in the "Integration - insert new rows" step.
The crazy thing is that in a step prior to this ("Export - load data"), the step succeeded and the data shows up in the output file!
So why is ODI trying to export the data again? And why am I getting an ORA error when the target is a file?
Any assistance is appreciated...
A frustrated noob!

Answer 1

I found the answer. But still not sure why this matters...
Following this tutorial, I recreated my mapping:
[http://www.oracle.com/technology/obe/fusion_middleware/ODI/ODIproject_table-to-flatfile/ODIproject_table-to-flatfile.htm]
I was still getting the same error. I reimported my IKM and found that the "Multi-Connections" box was unchecked before and now it was checked. I may have unchecked it in my trial & error.
Anyway, after running the mapping again with the box checked, the extract to a file worked.
So, I'm happy now. But, I am also perturbed with the function of the this checkbox and why it caused so much confusion within ODI.
