Using variables in Module parameters

Hi all,

I have a question about the Module parameters. I'm using Stefan Grube's blog (http://scn.sap.com/people/stefan.grube/blog/2007/02/20/working-with-the-payloadzipbean-module-of-the-xi-adapter-framework) to Zip XML files. I want to use the filename from the sender adapter and use it to name the XMl file in de Zip file.

As Stefan describes:

     Note:If you want to set the file name dynamically, you have to implement an adapter module. In thisWIKI pageyou find a sample code. You need SP20/SP12 for      this.

Is it required to create a custom adapter module or is this possible through Variable substition or an UDF (or something like that).

I hope someone can clear this out.

Thanks,

Koen
