How to set Automatic created Settlement Rule PER Work Orders

Dear all,

The issue is the next:

In the work order type defined, automatic settlement rule is created during release process. Then, work order created contains two rows, one for Total and the second one for Periodic, with the priority one set for Total.

Orders settlement process is run in massive process with KO8G transaction, so when the process type is not set to Periodic, all costs are settled in the selected period, not disguinshed by period.

I would like to modify the default settlement rule for only a periodic one, but I could not find any customizing point about it.

Does anybody know how to make settlement rule only a periodic one in customizing points, please?

Thanks
