  The SAP error message PMRP064 ("Entered quantity &1 must not exceed demand quantity &2") typically occurs in the context of production planning or material requirements planning (MRP) when a user attempts to enter a quantity for a production order, purchase order, or similar transaction that exceeds the available demand quantity for that item.
  Cause:
  
  Exceeding Demand: The primary cause of this error is that the quantity you are trying to enter (e.g., for a production order or a purchase requisition) exceeds the total demand quantity that has been calculated by the system for that material.
  Incorrect Demand Calculation: There may be an issue with how demand is calculated, possibly due to incorrect or incomplete data in the system.
  Planning Parameters: The planning parameters for the material may not be set correctly, leading to discrepancies in demand and supply.
  Stock Levels: If the stock levels are low or if there are existing reservations that are not accounted for, this can also lead to this error.
  
  Solution:
  
  Check Demand Quantity: Review the demand quantity for the material in question. You can do this by checking the MRP list or the stock/requirements list (transaction codes MD04 or MD05).
  Adjust Quantity: If the demand quantity is correct, adjust the quantity you are trying to enter to ensure it does not exceed the demand quantity.
  Review MRP Settings: Check the MRP settings for the material to ensure that they are configured correctly. This includes checking the lot size, safety stock, and other relevant parameters.
  Check Reservations: Look for any existing reservations or orders that may be consuming the demand quantity. You can use transaction codes like MB21 (Create Reservation) or MB22 (Change Reservation) to review this.
  Re-run MRP: If you suspect that the demand calculation is incorrect, you may need to re-run the MRP process to update the demand and supply situation.
  Consult Documentation: If the issue persists, consult SAP documentation or your internal SAP support team for further troubleshooting.
  
  Related Information:
