• What is the cause and solution for SAP error message AH431 - Enter a date starting from &1 ?

  The SAP error message AH431, which states "Enter a date starting from &1," typically occurs when a user attempts to enter a date that is earlier than the allowed date range defined in the system. This error is often encountered in various SAP modules, such as SAP HR (Human Resources) or SAP Project System (PS), where date validations are enforced.

  Check the Minimum Date: Review the minimum date allowed in the system. This can often be found in the configuration settings or by consulting with your SAP administrator.
  Enter a Valid Date: Adjust the date you are trying to enter to ensure it is on or after the minimum date specified by the system.
  Consult Documentation: If you are unsure about the date limits, refer to the relevant SAP documentation or user manuals for guidance on date entry.
  System Configuration: If the minimum date needs to be changed (for example, if business processes have changed), consult with your SAP Basis or configuration team to adjust the settings accordingly.
