No data transfer/ Time booked in CATS is not posted to controlling

Hi DBM Experts,

There is a message prompting out whenever I have done the Time Recording (Confirm/Clock off for the Service Order) as below:

            No data for transfer

                         Message no. LR301

Next I tried to create billing for my corresponding Service Order and I encountered an warning and error message as below:

Warning message:Time booked in CATS is not posted to controlling; billing not allowed

Error message:Event BILLING_CREATE cannot be processed (see long text)

Is the error and warning message above related to the message "No data for transfer" I received when I did the Time Recording?

Is the error message is related to CO object?

Please give me some advice on the issue above. Appreciate your kind respond.

Thank you.

Regards,

Dennis
