Dynamic Configuration with different value in case of Mutli Mapping - SFTP Adapter

Problem:

There has always been a problem of handling file name for multiple files created using a Multi Mapping, because one map can have only one value of the SOAP Dynamic Configuration Variable "FileName". The same problem can be easily resolved in case of SFTP Adpater.

Requirement:

You have one Sender Interface and two Receiver Interface. You have a Message Mapping with the Signature as

You want the two files to have different names. Something like FileHeader.<date>.txt and FileDetail.<date>.txt. One can say that you would not need to use dynamic configuration in this case, but if the requirement is to have <DATE> and not <DATETIMESTAMP>, you cannot use the standard process of addTimeStamp in the file.

Solution:

This can be achieved by a simple UDF:

And then you have to use the new functionality that is given in the SFTP Channel Dynamic Configuration:

Adapter Specific Message Attribute:
      Use Adapter Specific Message Attribute:
             Namespace: http://sap.com/xi/XI/System/File
             Filename Attribute Name: HdrFileName

Code

String strHdrFileName ="FileHeader."+date+".txt";
String strDtlFileName ="FileDetail."+date+".txt";

DynamicConfiguration conf = (DynamicConfiguration)container.getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey keyHdrFile = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","HdrFileName");
DynamicConfigurationKey keyDtlFile = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File","DtlFileName");

if(conf != null)
{
 conf.put(keyHdrFile,strHdrFileName);
 conf.put(keyDtlFile,strDtlFileName);
}

return "";
