I think you can do this by using the Context objects.
First get the Filename into your dummy element in target strcutre using UDF and create the context object between your dummy element and another element which holds the filename with equal conditon and use this context object in the receiver determination.
But I am not sure about it because i never tried this.
<b>UDF as follows:</b>
DynamicConfiguration conf = (DynamicConfiguration) container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create(
"http://sap.com/xi/XI/System/File",
"FileName");
DynamicConfigurationKey key1 = DynamicConfigurationKey.create(
"http://sap.com/xi/XI/System/File",
"Directory");
String source = conf.get(key);
String tar_dirname = "/mqm/mqmprod/temp/out/ " + source.substring(14,18); */
String tar_fname =source.substring(19,20);
String tar_dirname = source.substring(14,18);
conf.put(key, tar_fname);
conf.put(key1, tar_dirname);
return tar_fname;
Warm Regards,
