• What is the cause and solution for SAP error message KO305 - & is before valid period on the factory calendar ?

  The SAP error message KO305 indicates that there is an issue related to the validity period of a cost object, such as a cost center or internal order, in relation to the factory calendar. Specifically, the error message "is before valid period on the factory calendar" suggests that the date you are trying to use for a transaction or posting falls outside the valid period defined in the factory calendar for that cost object.
  Cause:
  
  Invalid Date: The date you are trying to use for the transaction is earlier than the start date defined in the factory calendar for the relevant cost object.
  Factory Calendar Settings: The factory calendar may not be set up correctly, or the validity period for the cost object may not cover the date you are trying to use.

  Adjust Cost Object Validity: If necessary, adjust the validity period of the cost object (e.g., cost center or internal order) to include the date of the transaction. This can be done in the configuration settings for the cost object.
  Consult with Configuration Team: If you do not have the necessary permissions to make changes, consult with your SAP configuration team or system administrator to resolve the issue.
