  The SAP error message PMRP083, which states "Change to reference top-level demand has been undone," typically occurs in the context of production planning and material requirements planning (MRP) when there is an issue with the demand management or planning process. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Demand Changes: The error often arises when there are changes made to the top-level demand (such as a sales order or forecast) that are not compatible with the existing planning data or MRP runs.
  Planning Parameters: Incorrect planning parameters or settings in the MRP configuration can lead to inconsistencies in how demands are processed.
  Locked Objects: If the demand or related objects are locked by another process or user, changes may not be applied, leading to this error.
  Data Inconsistencies: There may be inconsistencies in the master data (like BOMs, routing, or material master) that prevent the system from processing the demand correctly.
  
  Solutions:
  
  Check Demand Changes: Review any recent changes made to the top-level demand. Ensure that they are valid and do not conflict with existing planning data.
  Re-run MRP: After making necessary adjustments, re-run the MRP to see if the error persists. This can help in recalculating the requirements based on the updated demand.
  Review Planning Parameters: Check the MRP settings and parameters in the configuration to ensure they are set correctly for your planning scenario.
  Unlock Objects: If there are locked objects, identify the user or process that has locked them and resolve the issue. This may involve coordinating with other users or processes.
  Data Consistency Check: Perform a consistency check on the master data related to the materials and demands. Ensure that BOMs, routings, and material masters are correctly defined and up to date.
  Consult SAP Notes: Check the SAP Support Portal for any relevant notes or patches that may address this specific error message.

  User Authorizations: Ensure that users have the necessary authorizations to make changes to demand and planning data.
