Change Log activation for Work Orders

Hi all... i am a newcomer to this community. I have heard a lot about it & would like to utilise this platform for learning & knowledge sharing experience.

Well, I wanted to activate Change LOG for tracking changes made to Maintenance work orders.

I have tried it thru' SPRO

Plant Maintenance & Customer Service / Maintenance & Service Processing / Maintenance & Service Orders / Functions & Setings for Orders / Define Change Docs, Collective Purc. Req. Indicator, Operation No. Interval

I have ticked on the order types defined for my plant... without success.

Any other way to try this out ?

Thanking u in anticipation.

With Warm Regards...
