SAP ByD - Activity invalid or 'Tätigkeit ist am 31.12.2018 ungültig'


I'm trying insert a time record for an external service provider in his time sheed.

When I click on a date and start filling the fields I'm getting an error message Activity on 31.12.2018 not valid.

Original error message in german: "Tätigkeit ist am 31.12.2018 ungültig"

This error must have an connection to the order I choose, because with another order related to the same project, I'm able to save a time record.

Has anyone face a similar problem and what could be the reason for the error message?

Thanks in advance and regards

    Hi Sascha,

    Have you maintained the Actual hours worked for the service provider, also the system will not allow an employee to record the time against the project when there is no labor resource maintained for the employee or when the maintained labor resource is not valid for the employee so please maintain the resource with a combination of assigned Job role and employee assigned Cost Center.

    Please see these steps to check if the actual hours have been maintained:

    1. Go to the Business Configuration work center.
    2. Press Overview.
    3. Use an asterisk to search for all entries with Time Types <*Time Types*>.
    4. Click on Time Types - Germany
    5. Select Maintain Employee Time Types.
    6. Under Actual Hours worked, Service Activation the checkbox Time Sheet
    7. Click Save and Close or Close if checkbox is already selected.
    8. Press Activate for Time Recording Services.
    9. Choose Time Sheet.
    10. DEXXXX - Actual Hours Worked must be shown in Activated Time Types
    11. Go back to work center Business Configuration.
    12. Press Overview
    13. Use an asterisk to find entries with <*Time Recording*>
    14. Click on Default Values for Time Recording - Germany
    15. Default Value for Time Recording using Service Product must be Actual hours worked

    You can find the above steps in this KBA:

    Hope this helps,
