Error while handling special characters ( and &) in Sender File adapter

Question

Dear All,
Scenario: Third Party System --> (File adapter) SAP PI 7.1 (SP05) --> (Proxy) ECC
We are receiving CSV file and no mapping is required in PI as all the processing is being done by third party tool. But we are receiving special characters like ',",>,< and & in the csv file.
When we are using File Type as TEXT and File Encoding as ISO-8859-1 than we are getting error. We changed File Type to BINARY and than we are able to handle ',",> but having issue in handling < and &.
Any idea how we can handle it.
Please note trhere is no Mapping in SAP PI so cannot uise Java mapping.
Thanks a lot

Hey,
You can add ABAP Script in Receiver Proxy for eliminating or replacing with NULL or empty. Since you dont have mapping for formatting these kind of junks you can follow the above approach.
Else, you can remove the junks at OS level while running a small script and make it available to PI.
Or else, you need to create mapping for sender and recevier structure though it is same, then you add a very simple UDF for fine tune.
Use this UDF
Here a is the input value.
String b = "";
b = a.replaceAll(",", "0");
b = a.replaceAll("@", "0");
Like all the special characters you can take and replace with zero.
return b;
Thanx
