DCC ETL runs but does not map anything
![](http://jazz.net/_images/myphoto/311174b8534b9617c4de463fc7bd66af.jpg)
So I have asked other questions in the past about writing a custom ETL file for DCC.
I have finally written one, with the help of this forum, thank you!
So it's a custom mapping file, and the first one I wrote broke all the other jobs, but the second one I wrote didn't break anything, but didn't map anything either...?
Would anyone happen to know the specifications of a mapping file and maybe a clue as to why it wouldn't map?
Thank you

I haven't tried this myself, but you might try using one or both of these as guides/examples to help:
