• What is the cause and solution for SAP error message PMRP082 - Simulated change of top-level demand has been undone ?

  The SAP error message PMRP082, which states "Simulated change of top-level demand has been undone," typically occurs in the context of demand management and planning within the SAP system, particularly in the Production Planning (PP) and Materials Requirements Planning (MRP) modules. This message indicates that a simulation of changes to the top-level demand (such as a planned order or sales order) has been reversed or not executed as intended.
  Cause:
  
  Simulation Mode: The error often arises when changes are made in simulation mode, and the system does not allow the changes to be committed due to certain conditions not being met.
  Data Inconsistencies: There may be inconsistencies in the master data (like material master, BOM, routing) or transaction data (like existing orders) that prevent the simulation from being completed successfully.
  Planning Parameters: Incorrect planning parameters or settings in the MRP configuration can lead to this error.
  Locking Issues: If another user or process is locking the data that is being simulated, it can cause the simulation to be undone.
  
  Solution:
  
  Check Simulation Settings: Ensure that you are in the correct mode for making changes. If you intend to make permanent changes, ensure you are not in simulation mode.
  Review Master Data: Verify that all relevant master data (material master, BOM, routing) is correctly set up and does not contain errors or inconsistencies.
  Analyze MRP Settings: Review the MRP settings and parameters to ensure they are configured correctly for your planning scenario.
  Check for Locks: Use transaction codes like SM12 to check for any locks on the data you are trying to simulate. If locks are found, coordinate with the relevant users to resolve them.
  Run MRP Again: If the issue persists, try running the MRP process again to see if it resolves the issue.
  Consult Logs: Check the MRP logs for any additional error messages or warnings that could provide more context on why the simulation was undone.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MD01 (MRP Run), MD04 (Stock/Requirements List), and MD02 (Single-item, Multi-level MRP).
  SAP Notes: Search for SAP Notes related to PMRP082 for any specific patches or updates that may address known issues.
  Documentation: Review SAP documentation on MRP and demand management for best practices and troubleshooting steps.
  Support: If the issue cannot be resolved internally, consider reaching out to SAP support for further assistance.
  
  By following these steps, you should be able to identify the cause of the PMRP082 error and implement a solution to resolve it.
