  The SAP error message AJ450, which states "Fields not ready for input in &1 schema step, &2 variant are filled," typically occurs in the context of payroll processing or when working with schemas in the SAP HR module. This error indicates that certain fields in the specified schema step are not available for input, even though the variant (which defines the parameters for the payroll run) has been filled.
  Cause:
  
  Schema Configuration: The schema step may not be configured to accept input for the fields in question. This can happen if the schema is set up incorrectly or if certain fields are not intended to be modified at that step.
  Field Status: The fields may be set to "display only" or "not ready for input" due to the configuration in the schema or the variant settings.
  Incorrect Variant: The variant being used may not be appropriate for the current processing context, leading to conflicts in field availability.

  Solution:
  
  Check Schema Configuration: Review the schema configuration in transaction PE01 or PE02. Ensure that the fields in question are correctly set up to allow input at the specified step.
  Review the Variant: Check the variant settings in transaction PE03. Ensure that the variant is appropriate for the payroll run and that it aligns with the schema configuration.
  Field Status Maintenance: If certain fields are not meant to be input fields at that step, consider whether the schema needs to be adjusted to allow for input or if the process should be modified to accommodate the existing configuration.
  Authorization Check: Verify that the user has the necessary authorizations to input data in the specified fields. This can be checked in transaction SU53 or by consulting with your security team.
