• What is the cause and solution for SAP error message RMPU209 - Function not possible for simultaneous quantity input ?

  The SAP error message RMPU209, which states "Function not possible for simultaneous quantity input," typically occurs in the context of inventory management or production planning when there is an attempt to perform an operation that is not allowed due to the current state of the system or the data being processed.
  Cause:
  
  
  Simultaneous Quantity Input: This error often arises when there are multiple transactions or processes trying to update the same quantity at the same time. For example, if two users are trying to post goods movements for the same material simultaneously, the system may not allow this due to data integrity constraints.
  
  
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If a record is locked by one transaction, another transaction trying to access it may trigger this error.
  
  
  Configuration Issues: There may be configuration settings in the system that restrict certain operations when simultaneous quantity inputs are detected.
  
  
  User Authorizations: Sometimes, the error can be related to insufficient user authorizations to perform the desired operation.
  
  
  Solution:
  
  
  Check for Concurrent Transactions: Ensure that no other users or processes are trying to perform the same operation on the same material or quantity. If possible, coordinate with other users to avoid simultaneous inputs.
  
  
  Wait and Retry: If the error is due to a temporary lock, waiting for a few moments and then retrying the operation may resolve the issue.
  
  
  Review System Logs: Check the system logs (transaction SM21) for any additional information regarding the error. This may provide insights into what caused the lock or conflict.
  
  
  Transaction Codes: If you are using specific transaction codes, ensure that they are being used correctly and that the necessary prerequisites are met.
  
  
  Configuration Review: Consult with your SAP Basis or configuration team to review any settings that may be causing this restriction. They may need to adjust the configuration to allow for the desired operations.
  
  
  User Authorizations: Verify that the user has the necessary authorizations to perform the operation. If not, the user may need to be granted additional permissions.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error. There may be patches or updates that resolve known issues.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MB1A (Goods Withdrawal), MB1B (Transfer Posting), or MIGO (Goods Movement) that may be involved in the process.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Documentation: Review SAP documentation related to inventory management and goods movements for best practices and troubleshooting steps.
  
  If the issue persists after trying the above solutions, it may be beneficial to escalate the matter to your SAP support team or consult with SAP directly for further assistance.
