• What is the cause and solution for SAP error message PMRP029 - No top-level demand found for planning ?

  The SAP error message PMRP029 "No top-level demand found for planning" typically occurs in the context of Material Requirements Planning (MRP) when the system is unable to find a top-level demand (such as a sales order, production order, or planned independent requirement) for the material being planned. This can happen for several reasons, and understanding the cause is essential for resolving the issue.
  Causes:
  
  Missing Demand: There may be no sales orders, production orders, or planned independent requirements for the material in question.
  Incorrect Planning Parameters: The planning parameters for the material may not be set correctly, leading to the system not recognizing any demand.
  Material Status: The material might be set to a status that prevents it from being planned (e.g., "Blocked" or "Inactive").
  MRP Type: The MRP type assigned to the material may not be appropriate for the planning scenario (e.g., if it is set to "ND" - No MRP).
  Plant or Storage Location Issues: The material may not be assigned to the correct plant or storage location, or the plant may not have any demand.
  Planning Horizon: The planning horizon may not include the period for which demand exists.
  
  Solutions:
  
  Check Demand: Verify if there are any sales orders, production orders, or planned independent requirements for the material. If not, create the necessary demand.
  Review Planning Parameters: Ensure that the planning parameters for the material are set correctly in the material master (transaction code MM02).
  Check Material Status: Confirm that the material is not blocked or inactive. You can check this in the material master data.
  Verify MRP Type: Ensure that the MRP type is appropriate for the material. If it is set to "ND," consider changing it to a type that allows planning (e.g., "PD" for MRP).
  Check Plant and Storage Location: Make sure the material is assigned to the correct plant and storage location and that these are active.
  Adjust Planning Horizon: If necessary, adjust the planning horizon in the MRP settings to include the period for which demand exists.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like MM02 (Change Material), MD04 (Stock/Requirements List), and MD01 (MRP Run) to investigate and resolve the issue.
  MRP Configuration: Review the MRP configuration settings in SPRO (Customizing) to ensure that they align with your business processes.
  Documentation: Refer to SAP documentation or help files for detailed explanations of MRP processes and settings.
  
  By following these steps, you should be able to identify the cause of the PMRP029 error and implement the necessary solutions to resolve it.
