Dynamic filenames in RFC to FTP scenario

Question

Hi all,
i am working on two interfaces, and have doubts about each of them, here they go:
- Scenario1: RFCtoFTP --> some info is sent in some fields and i need to use these fields to generate files with the proper filenames (by concateating them or whatever). In addition, depending on the filenames, XI will have to send them to the proper directory in target system.
Lets say, XI receives and rfc wit two fields: field1 and field2; i´d need to create a file named "field1field2.txt" and send it to the field1 directory.
- Scenario2: FTPtoRFC --> XI takes a file and creates target fields with the value of several strings that are part of the filename it took.
Lets say: XI takes a file named "field1field2field3.txt" and maps to three fields of the respective RFC; field1; field2; field3
I d rather not use BPM if possible.
Could you please guide me about some steps in order to be able to build there two scenarios?
best regards,
David

Hi Sebin,
In scenario1, i am receiving a field called FILENAME, and i have created a UDF with your code (and with one input parameter FILENAME:
public String DynamicConfiguration(String FILENAME,Container container){
DynamicConfiguration conf = (DynamicConfiguration)
container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey dck = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String filename = "FILENAME";
conf.put(dck,filename);
However when i insert the UDF in the graphical mapping, the function comes with an input and output parameters, i know what to do with the input but no with the output.
Question is, which is the target field of the output of the UDF??
In scenario2, May i use the Michal´s UDF?
public String DynamicConfiguration(Container container){
DynamicConfiguration conf = (DynamicConfiguration)
container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","FileName");
String ourSourceFileName = conf.get(key);
return  ourSourceFileName; 
I think this would take the filename and later on i could split this name into several target fields.
Could you please help? i am stuck on this.
Thanks in advance and best regards,
david
