64265 - Details

• The SAP error message 64265, "Not possible to change units which are already allocated," typically occurs in the context of inventory management or production planning when you attempt to change the units of measure for materials that have already been allocated or reserved in the system. This can happen in various scenarios, such as during goods movements, production orders, or when managing stock levels.
  
  Cause:
  
  Allocated Stock: The stock in question has already been allocated to a specific order or process, making it impossible to change the unit of measure.
  Open Transactions: There may be open transactions or processes that are using the stock, preventing changes to its unit of measure.
  Configuration Settings: The system settings or configuration may restrict changes to units of measure for allocated stock.
  
  
  Solution:
  
  Check Allocations: Review the allocations for the material in question. You can use transaction codes like MB52 (List Warehouse Stocks on Hand) or MB5T (Stock in Transit)
