• What is the cause and solution for SAP error message 64521 - Sale of only maximum & units possible ?

  The SAP error message "64521 Sale of only maximum & units possible" typically occurs in the context of sales order processing, particularly when dealing with stock levels and availability. This error indicates that the quantity requested for sale exceeds the available stock for the specified material.
  Cause:
  
  
  Insufficient Stock: The primary cause of this error is that the quantity being ordered exceeds the available stock in the system. This can happen if:
  
  The stock has been depleted due to previous sales.
  There are restrictions on stock availability (e.g., stock is reserved for other orders).
  The material is subject to allocation or has been blocked for some reason.
  
  
  
  Configuration Issues: Sometimes, the configuration settings in the material master or sales order processing may lead to this error, especially if there are specific rules governing stock availability.
  
  
  Sales Order Type: Certain sales order types may have restrictions on how much can be sold based on the stock levels.
  
  
  Solution:
  
  
  Check Stock Levels: Verify the current stock levels for the material in question. You can do this using transaction codes like MMBE (Stock Overview) or MB52 (List Warehouse Stocks on Hand).
  
  
  Adjust Order Quantity: If the stock is indeed insufficient, you may need to adjust the order quantity to match the available stock. 
  
  
  Check Reservations: Look for any existing reservations or allocations that may be affecting the available stock. You can use transaction code MB21 to check reservations.
  
  
  Review Material Master Settings: Ensure that the material master settings are correctly configured, particularly in the sales and distribution (SD) view. Check for any restrictions that may be in place.
  
  
  Consult with Inventory Management: If stock levels are low, consult with the inventory management team to see if additional stock can be procured or if there are any pending deliveries that can fulfill the order.
  
  
  Use Backorder Processing: If applicable, consider using backorder processing to allow the order to be placed and fulfilled once stock becomes available.
