PM Service order creation from EL27 in IS-U

Hi experts,

I am trying to configure the creation of service orders (Work Management) from the transaction EL27, as a consecuence of meter readings implausible results. By clicking in "PM Service" the system does nothing really. I have been trying to figure out how to make it work but I couldn't. I don't see anywhere in the SPRO related to this configuration, apparently.

Please, someone to help me here on how to configure this order generation?

Thanks!
