Maintenance Order Settlement Error

http://www.stechno.net/sap-notes.html?view=sapnote&id=179533

Hi Experts;

At the time of settlement run for a maintenance order on KO88

I received the mentioned error by system in the attached test file.

And found an SAP Note which is mentioned on the attached link.

- Following point number 1 in the solution section and set the order for TECO technical complete but it didn't work.

- Then searching for the Accrual Calculation customization to check the FLAG for "Settlement to FI" as mentioned on point number 2, I couldn't reach it on the SPRO, I found many Accrual Calculation options for different reasons but no one of them related to my issue and I didn't find that CHECK BOX for "Settlement to FI" at any of them.

So can someone kindly guide where to find such place to custom the settings to overcome such error ?

OR

Any else way to solve that error please ASAP because of the Year End Closing procedures ?

Thanks in advance;

Best regards;
