Error Configuration (ZFM Name) is not active which means no WSDL

Hi Experts,

After creating web service from a FM when I am trying to open the WSDL file via link

"Open Web Service navigator for selected binding" from SOA manager (Check box is filled with the binding information) I am getting following error.

"Configuration (FM NAME) is not active which means no WSDL can be generated "

Could you please let me know what can be the reason and what I am supposed to do?

Regards,

Sandeep
