Validating file in PI

Question

Hi Folks,
    In my scenario.  PI will be getting a file in following format.
    Header
    Item
    Item
    Header
    Item
    Item
    End Records
    PI have to check if 'End Record' exists in the file. If not, then Alert need to be triggered. I am not sure how the scenario can be handled without using BPM.
   Please help me if anybody is aware of the scenario.
Thanks & Regards,
Punit

Hi Abhishek,
Thanks.I just mentioned how I handled such a requirement.
You are right,handling it at Receiver Determination level would be good so as not to reach Message Mapping level.
I had to check if a field in Excel is blank(when we converted this Excel into XML,then this blank is replaced by " in XML)
In such case,I had to raise an exception.
So I created a UDF:
public String throwErrorOnInvalidValue(String a,Container container){
if(a.equals("\""))
throw new RuntimeException("Invalid Value: Value should be numeric");
else
return a;
