• What is the cause and solution for SAP error message KM121 - Field & must always be time-dependent ?

  The SAP error message KM121 ("Field & must always be time-dependent") typically occurs in the context of SAP Controlling (CO) or SAP Project System (PS) when you are trying to enter or modify data that requires a time-dependent characteristic, but the system does not have the necessary time-dependent data.

  Missing Time-Dependent Data: The field in question is expected to have time-dependent values, but the required data for the specified time period is either missing or not properly maintained.

You can do this by navigating to the relevant master data transaction (e.g., KS01 for cost centers) and checking the validity periods.
  
  
  Maintain Validity Periods: If the data is missing, you may need to create or update the master data to include the necessary time-dependent entries. Make sure to specify the correct validity periods for the data.
  
  
  Review Configuration: If you suspect a configuration issue, review the settings in the controlling area or project settings to ensure that they are set up to allow for time-dependent data. This may involve checking the configuration in SPRO (SAP Customizing Implementation Guide).
