• What is the cause and solution for SAP error message FKKEXC266 - Postings were repeated in simulation mode ?

  The SAP error message FKKEXC266 indicates that there are repeated postings in simulation mode. This typically occurs in the context of the Contract Accounts Receivable and Payable (FI-CA) module when you are trying to simulate a posting that has already been processed in the same session.
  Cause:
  
  Repeated Simulation: The error usually arises when the same transaction is attempted to be simulated multiple times without any changes. SAP detects that the same posting has already been processed in the current session.
  Incorrect Configuration: There may be issues with the configuration of the posting logic or the simulation settings.
  Data Integrity Issues: There could be underlying data integrity issues that cause the system to think that the same posting is being attempted again.
  
  Solution:
  
  Check for Duplicates: Ensure that you are not trying to simulate the same transaction multiple times. If you need to simulate a different transaction, make sure to change the relevant parameters.
  Clear Session: If you are in a testing environment, you can try to clear the session or restart the transaction to reset the simulation state.
  Review Configuration: Check the configuration settings related to the posting logic in the FI-CA module to ensure that they are set up correctly.
  Use Different Parameters: If you need to simulate a similar transaction, try changing some parameters (like amounts, dates, etc.) to avoid the duplication.
  Consult Documentation: Refer to SAP documentation or notes related to the specific transaction you are trying to simulate for any known issues or additional guidance.
  
  Related Information:
