Publish web service from a BAPI

Hi all,

I'm trying to publish a WebService from the BAPI_MATERIAL_AVAILABILITY and followed the steps listed bellow:

1. Create a web service definition from the BAPI through Utilities menu.
2. Enter into SOAMANAGER transaction.
3. Select Service Administration -> Web Service Configuration option.
4. Select my service definition then push the Create Service button.
5. Set the name for the service and the binding.
6. Set the provider security parameters.
7. And when I click on finish I get the error: Error: Getting Service Definition '<service definition name>' for registry 'SR_LOCAL' failed: Application Error: Application not registered with Application Key 00215AC855101ED49D8954A1A60166BF

Does anybody knows what am I missing?

Best regards,

Gregory.
