Optional lines in Flatfile in biztalk

Question

I have to flatfiles that i need to convert into UBL using Biztalk.

Everything is fine until I reach the end of the flatfiles.

One of them looks like this

RZ0100120400R;RZ01-00120400;RAZER MAMBA 2012 EL;2;739,77;2013.06.12
RZ0100580100R;RZ01-00580100;RAZER NAGA 2012;1;482,38;2013.06.12
RZ0400590100R;RZ04-00590100;RAZER TIAMAT EXPERT;2;605,3;2013.06.12

TOTA;L FAKTURAVÆRDI;EKSKL. MOMS;;18.667,30;

the other one like this:

382908;382908;Anymode Samsung Gal;4;88,87;2013.06.13
382909;382909;Anymode Samsung Gal;4;88,87;2013.06.13
ANYMODESAMSUN;ANYMODE SAMSU;ANYMODE ANYMODE SAM;4;88,87;2013.06.13
;;;;;
TOTA;L FAKTURAVÆRDI;EKSKL. MOMS;;8.116,31;

If I make a schemas for one the other one won't work. So my question is. How do I make a schema that can take both of them, without problems?? I just need something to ajust for the empty line in the first example. I am using Visual Studio Flatfile Wizard.

Answer 1

You could make the record/line in question as well as all of its child field elements optional (Min Occurs = 0).

Sample Schema (tested with both sample flat files provided...):
