  The SAP error message PMRP025, which states "Simulation top-level demand &1 not found," typically occurs in the context of production planning and material requirements planning (MRP) when the system is unable to find the specified top-level demand during a simulation run. This can happen for various reasons, and understanding the cause is essential for resolving the issue.
  Causes:
  
  Missing Demand Data: The specified top-level demand (e.g., a sales order, planned order, or forecast) may not exist in the system or may have been deleted.
  Incorrect Simulation Parameters: The parameters used for the simulation may not be set correctly, leading to the system not being able to locate the demand.
  Data Consistency Issues: There may be inconsistencies in the master data or transaction data that prevent the system from recognizing the demand.
  Authorization Issues: The user may not have the necessary authorizations to access the demand data.
  Configuration Issues: There may be configuration settings in the MRP or planning area that are not set up correctly.
  
  Solutions:
  
  Check Demand Data: Verify that the top-level demand exists in the system. You can do this by checking the relevant sales orders, planned orders, or forecasts.
  Review Simulation Parameters: Ensure that the parameters used for the simulation are correct. This includes checking the planning version, planning horizon, and any other relevant settings.
  Data Consistency Check: Run consistency checks on the master data and transaction data to identify any discrepancies. This can include checking material master records, BOMs, and routing data.
  Authorization Check: Ensure that the user has the necessary authorizations to access the demand data. This may involve checking user roles and permissions.
  Configuration Review: Review the configuration settings related to MRP and planning areas to ensure they are set up correctly. This may involve consulting with a functional consultant or SAP Basis team.
