• What is the cause and solution for SAP error message TA012 - Parameter changed after last run ?

  The SAP error message TA012 ("Parameter changed after last run") typically occurs in the context of background job processing or when executing a transaction that relies on certain parameters that have been modified since the last execution. This error indicates that the parameters used in the previous run of the job or transaction have been altered, which can lead to inconsistencies or unexpected behavior.
  Cause:
  
  Parameter Changes: The most common cause is that the parameters (such as selection criteria, configuration settings, or user-specific settings) have been changed after the last execution of the job or transaction.
  Job Scheduling: If a background job is scheduled to run at specific intervals, and the parameters are modified in between runs, this error may occur.
  User-Specific Settings: If the job or transaction relies on user-specific settings that have been changed, it can trigger this error.
  
  Solution:
  
  Review Parameter Changes: Check the parameters that were used in the last run and compare them with the current settings. Identify any changes that may have been made.
  Revert Changes: If the changes to the parameters were not intended, revert them to their previous values and re-run the job or transaction.
  Adjust Job Scheduling: If the job is scheduled to run automatically, ensure that the parameters are stable and not frequently changed between runs.
  Test in Development: If possible, replicate the issue in a development or test environment to understand the impact of the parameter changes.
  Consult Documentation: Review SAP documentation or notes related to the specific transaction or job to understand any known issues or additional configuration that may be required.
