Scheduling parameters for maintenance order have not been entered

Hi,

We have existing plants. Added a new one ZA05. When creating a new Service Order with order type ABCD I get the error:

Scheduling parameters for maintenance order have not been entered.

The issue is that NONE of the EXISTING plants have been maintained for order type ABCD in OPU7 (specify scheduling parameters)... so why is this new plant getting the error?

Thanks
