Mapping error: Content is not allowed in prolog

[Former Member]

Hi All,

I have a File-to-File scenario. It only transports the flat file to target folder with the same name. But at the same time it creates an empty trigger file with same file name, but the file extension is .trg.  The original developer set up a UDF in mapping to get the file name and change the extension to .trg and map it to target root node. That is all in mapping. In interface determination, it has one sender (flat file), 2 receivers to create 1 same flat file with no mapping and 1 trigger file with mapping. It has been working except today I got error saying "Mapping error: Content is not allowed in prolog". Not sure what caused that, since the content doesn't matter (and wasn't used) in mapping. The flat file is always the same format - pipe delimited file. Any one has an idea?

Thanks a lot!

Hi,

Please check the blog below:

First try removing SWC reference from Sender agreement and then removing SWC reference from receiver determination.

One of these would work.

hope it helps!

Hi Ambrish,

Thanks for the link. However, looks like it still make no difference. Now I have removed SWCV in everywhere and test 3 times. Looks like no failure now. I will keep watching. If it works, I will come back and update, so other people could benefit.

Hi,

Hi Michal,

Thanks for the response. I checked history. The latest change was made on April 22,2013. And the objects went alive on May 5th. It has been working. And I tested today with the same file 5 times, 2 failed, 3 successful.
