Dynamic Config for Target directory

Question

Hello Experts,
My interface is from MQ (JMS) to FILE.
I have one sender and one receiver.
I have the Lockbox data placed into the single Queue for 2 countries (AU u2013 Australia and NZ u2013 Newzeland)
Point 1: My PI Interface Picks the lockbox data up from the Queue, then the respective file (dynamically by using dynamic configuration) is being created based on the condition in mapping.
Here my mapping logic:
SourceStrucutre                                                       ReceiveStrucutre                          
     Filed1               Filed1
     Filed2               Filed2
INPUT -
 FIXED VALUES u2026u2026u2026..> UDF1 u2026u2026u2026> ReceiveStrucutre ( root node)
Expected input values for INPUT: ABC and XYZ (ABC for AU and XYZ for NZ)
Expected values in FIXED VALUES: ( if ABC -  create file name  FILE1.TXT; if XYZ -  create file name FILE2.TXT)
The below UDF is mapped to root node of Receiver Structure.
UDF1 code: ( with single Argument with name : arg)
DynamicConfiguration conf = (DynamicConfiguration) container
    .getTransformationParameters().get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
conf.put(key, arg);
return "";
the above mentioned logic works fine and am able to generate the file names (FILE1.TXT & FILE2.TXT ) in the target directory ( /tmp/common ) which mentioned in the receiver file adapter.
Point 2:
My Requirement is to generate the target directory dynamically based the file name generated..
Expected Target directory:
/tmp/AU/FILE1.TXT for the file FILE1.TXT
/tmp/NZ/FILE2.TXT for the file FILE2.TXT
I know we can do this by writing another UDF2 (DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "Directory"); for the directory and by making ASMA ticked for Directory in communication channel..
My question is how to map the two UDFs to the same root node of receiver..
Valuable inputs are much appreciated!!
Thanks,
Kumar

Answer 1

what i mean is have :
DynamicConfigurationKey key = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "FileName");
and
DynamicConfigurationKey key1 = DynamicConfigurationKey.create("http://sap.com/xi/XI/System/File", "Directory");
conf.put(key, arg)
conf.put(key1, value for Directory)
If you are worried on how to map two UDFs to root node then FYI you can map the o/p of the UDFs to any node in your target structure......it wont cause any harm....
If you say no node is free then you can have two inputs to your UDF and then in the return statement send out the value that you want to pass to the target node (presently you are using return"".......if applying above then you will have return arg2)....
