how exclude matching rows in 2 flat files using informatica?

i have flat file (source) data looks (normally lot more data):

1,2,3 4,5,6

and second flat file (source) this:

1,2,3

i want result (target) flat file looks this:

4,5,6

i know in sql there exclude (opposite of intersect) job. doing flat files , informatica.

i pretty new informatica. have been doing month. might rather obvious. if tell me tranformations use great.

you can use union transformation union result sets both files. give following result set .

col1, col2, col3 ----------------- 1,2,3 4,5,6 1,2,3

after use aggregator transformation , select these ports (and ever want group consider them duplicate) , count in aggregator transformation.

after aggregator (new column count => total_count) ---------------------------------------------------- col1, col2, col3,total_count ----------------------------- 1,2,3,2 4,5,6,1

the next step simple, pass them through filter transformation , use following filter condition ignore rows have duplicates.

total_count = 1

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
