Filename based on varying payload elemet.

Question

Hi All,
My file name is dependent on the payload.The file name is not based on a fixed element in the payload but varies with the payload type (although the schema is the same for all).
Variable Substitution will not work as the substitutation itself is not fixed.
I thought of writing a module and change the file name before CallSAPAdapter is invoked.
Basically I am planning to use Adapter Specific Attibute.This way the Dynamic configutaion will be filled and I an provide the value in my module.
Has anyone tried this.
Any other idea on how to manipulate the Filename otherwise without having multiple Receiver defined.
Please note ,the Sender Adapter in this case is IDoc and using UDF (in mapping) to update DYNAMIC_CONFIGURATION using Adapter Specific Atribute may not work.
Thanks in Advance,
Regards,
Bikram

Hi Sravya,
In the example you mentioned, "conf" or the  "valueOld" will be null as there is no dynamic configuration defined in the sender adapter (IDoc in my case).
// access dynamic configuration
      DynamicConfiguration conf = (DynamicConfiguration) param.get(
          StreamTransformationConstants.DYNAMIC_CONFIGURATION);
      // read value
      String valueOld = conf.get(KEY_FILENAME);
      if (valueOld == null) {
          throw new StreamTransformationException(
              "Filename is missing. ");
I tried the following in UDF and "conf" is null.
DynamicConfiguration conf = (DynamicConfiguration) container
.getTransformationParameters()
.get(StreamTransformationConstants.DYNAMIC_CONFIGURATION);
Any other idea ?
How Can I access the DynamicConfiguration in a module ?
