Hi Can any one provide me UDFfor following Requirement.

My source file name is like this XXXX081090001 and i want reciver file name as XXXXMT940.

Where MT940 is constant and XXXX is first 4 digits of Source file name.

Note that First four digits of Source file name can change.

Example :- Source file name ABC081090001 -

---

Target should be ABCMT940

and if Source file name is XYZ091100002 -

Hi,

try this code,

udf is context type,

single input i.e your source name

for(int i=0;i<sourceName.length;i++)

{

String store = "";

store = sourceName<i>.substring(0,4);

store = store + "MT940";

result.addValue(store);

}

Hi,

try this one...

DynamicConfiguration conf = (DynamicConfiguration)

container.getTransformationParameters().get

(StreamTransformationConstants.DYNAMIC_CONFIGURATION);

DynamicConfigurationKey key = DynamicConfigurationKey.create

("http://sap.com/xi/XI/System/File","FileName");

String input = conf.get(key);

String s1 = input.substring(0,4);

String s2 = "MT940";

String newfile = s1.concat(s2);

conf.put(key,newfile);

return (newfile);

Consider to set "Filename" in the Adapter Specific Message Attributes in FileAdapter.

Hi Dinesh,

I just tried the mapping and it works. If you use test functionality of message mapping you must deactivate lines 1 - 6 and line 10 of my solution because this is only filled on runtime. Instead of line 6 use the following: String input ="XXXX1081somewhat";

Hi,

you could do it with the standard functions:

substring, concat and constant

Use the substring function for taking the first 4 chars and

then concat the result with constant (MT940).
