File-to-File Scenario: Parsing issue

Hey experts,

I had to work with idoc-to-file or file-to-file several times, and i noticed that sometimes if one data to map to the file was incomplete it caused several errors mapping, there's any way to fix that?

Let me explain with an example:

XML structure: 3,4,5,(missing field),7

If the parsing corresponding to "6" is smaller than 7 i would get an error because the transmission would be: 3,4,5,7

In most of cases these are mandatory fields, but i'm curious as if we have any other choice to find that error, because in big xml files is really hard to check which data is missing and why

There's any way to leave with blanks to avoid errors and the displacement of data? => 3,4,5, ,7

Thanks in advance,
