RE: Suppress or stripping of some digits in XI with out effecting others

Question

In  POS, the Employee Id (of the Store Rep) who does the sale is his PEIN.  The design of POS does not allow the employee to work in more than 1 store. Therefore we-are exploring a "corrective" solution which - ideally would not affect POS+ as follows:
XYZ  team will "pass"  an employee ID which is made of  his PEINstorecode (which would fit in the 12 digits alphanumeric employee code in POS Employee table).  In other words, the new employee ID in POS+ will have the official  PEIN (7 digitis) suffixed with storeId as the next 5 digits
All sales transactions will carry this "new" employee ID. HOWEVER, when the sales transactions is passed over to XI ,  "a code fix"/or/ a data transformation / or / data mapping whithin XI (?) would have to be effected within XI to "strip" the extra 5 StoreId digits?
In the "hypothetical" scenario I described,  the the input file from POS+ to XI will display an Employee id with the new format as " PEIN Nostoreidincremental digit"  (74digitsx) 
In my XML example ,
<StoreID>4152</StoreID>
  <TransactionID>8962</TransactionID>
  <RegisterTransNumber>2607</RegisterTransNumber>
  <TransactionCode>101</TransactionCode>
  <EmployeeID>6020540</EmployeeID>
ithe new Employee ID will show  : 602054041521    with the last digit incrementing from 1 to 9 .
What can be done in XI to parse the information and get it back to an Employee ID as for example EmployeeID>6020540 , so that the remaining XI, SAP , SAP BW streams is left intact?  Please advise on this 
How can we resolve this in XI?
Thanks in advance

Hi Amarnath,
If you want to remove the last 5 then create a value UDF with one input argument 'a' and name as removelastfive and add this code:
Imports:  java.;*
   //write your code here
String str = a.substring(0, a.length()-5);
return str;
Then you map like this:
input --> removelastfive(udf) --> output.
