• What is the cause and solution for SAP error message EEWM_APPOINTMENT036 - Function not possible with appointment that has already been selected ?

  The SAP error message EEWM_APPOINTMENT036 indicates that an operation cannot be performed on an appointment that has already been selected. This typically occurs in the context of the SAP Extended Warehouse Management (EWM) module, where appointments are used to manage the scheduling of inbound and outbound deliveries.
  Cause:
  The error usually arises due to one of the following reasons:
  
  Appointment Already Selected: The appointment you are trying to modify or perform an action on has already been selected or processed by another user or transaction.
  Concurrency Issues: Multiple users or processes may be trying to access or modify the same appointment simultaneously, leading to conflicts.
  System Locking Mechanism: SAP uses locking mechanisms to prevent data inconsistencies. If an appointment is locked by another transaction, you will not be able to perform actions on it.
  
  Solution:
  To resolve the error, you can try the following steps:
  
  
  Check Appointment Status: Verify the status of the appointment in the system. If it is already selected or in use, you may need to wait until the other transaction is completed.
  
  
  Refresh the Data: Sometimes, simply refreshing the screen or reloading the data can help. This ensures you are working with the most current information.
  
  
  Identify Locking Transactions: Use transaction codes like SM12 (to check for locks) or SM21 (to view system logs) to identify if another user or process is holding a lock on the appointment.
  
  
  Communicate with Users: If you find that another user is working on the same appointment, communicate with them to understand their actions and coordinate accordingly.
  
  
  Retry the Operation: After confirming that the appointment is not locked or in use, try to perform the operation again.
  
  
  Consult Documentation: Review SAP documentation or help resources for any specific guidelines related to the appointment management process in EWM.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for further assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM, such as /SCWM/APP for managing appointments.
  User Roles and Authorizations: Ensure that you have the necessary permissions to perform actions on appointments.
  System Configuration: Check if there are any specific configurations in your EWM setup that might affect appointment handling.
  
  By following these steps, you should be able to address the EEWM_APPOINTMENT036 error effectively.
