Problem merging XML and XDP

Hello!

I created a process in Workbench, using Output ES, to merge XDP to XML files and create PDF documents. It works fine.

Now I've created an 1.1 version of this same solution to do exactly the same thing, changing only the XDP model and the correspondent XML.

I generated the XML file from Designer using the XDP template. When previewing in Desiner it works just fine.

However, when I tried to run the process with this new pair of XDP-XML files, I got this error message:

Reason of failure is-----ALC-OUT-001-608: Could not parse records from data file. Record name or record level may be incorrect.

I have no idea as to why this is happening, once the XML has been generated from the same XDP I'm working with in Workbench.

Please, any hints?

Thank you!
