webdynpro Application and RFC problem

Hi all,

I have a webdynpro application that has a model with a RFC that allow users store a file into the disk, but when I try to run the application and pressed the button that make the call to the RFC I get the following error:

Exception condition "NO BATCH" raised, error key: RFC_ERROR_SYSTEM_FAILURE

Does anyone know anything about this error?..Please help me!

Thanks in advance,

Jesus.
