• What is the cause and solution for SAP error message MD06425 - Simulative mode chosen ?

  The SAP error message MD06425, which states "Simulative mode chosen," typically occurs in the context of Material Requirements Planning (MRP) or similar planning processes in SAP. This message indicates that the system is running in a simulation mode rather than executing actual changes or updates to the planning data.
  Cause:
  The primary cause of this error message is that the MRP run or planning process has been initiated in a simulation mode. This mode is often used for testing or analysis purposes, allowing users to see the potential outcomes of a planning run without making any actual changes to the database or production planning data.
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check the Planning Parameters: Review the parameters set for the MRP run or planning process. Ensure that the "Simulative mode" option is not selected if you intend to perform an actual planning run.
  
  
  Change the Execution Mode: If you are using transaction codes like MD01, MD02, or similar for MRP runs, ensure that you are not selecting the "Simulative" option. You may need to uncheck any options that indicate a simulation.
  
  
  Review User Authorizations: Ensure that you have the necessary authorizations to perform a non-simulative MRP run. Sometimes, user roles may restrict certain actions.
  
  
  Consult Documentation: If you are unsure about the settings or the implications of running in simulation mode, refer to SAP documentation or consult with your SAP Basis or functional team.
  
  
  Testing: If you are testing changes or configurations, it may be appropriate to leave the simulation mode enabled. In this case, you can analyze the results and make adjustments as needed before executing a real planning run.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD01 (MRP Run), MD02 (Single-item, single-level planning), and MD03 (Single-item, multi-level planning).
  MRP Configuration: Understanding the configuration settings for MRP in your SAP system can help you avoid unintended simulation runs.
  SAP Notes: Check for any SAP Notes related to MRP and simulation modes, as they may provide additional insights or updates regarding this error message.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP's support portal for further assistance.
