Result Analysis for Refurbishment order

Hi Experts,

Could you please explain, can we calculate result analysis for refurbishment orders, I have created the RA key wip cost element ,selected internal and service orders w/o revenue in OKG9 and other WIP setting, I have assigned this TA key to order type in OIOF, I have created one refurb order, released and confirmed the order, now I have to do month end activity like RA calculation in KKA1 and than settlement.

When i am trying to execute KKA1 I am getting this message " Results analysis data was not changed

Message no. KJ240"

Could you please advise me how I need to fix this issue.

Appreciate if you can explain the month end process for refurbishment order in detail.

Regards,
