• What is the cause and solution for SAP error message /SAPAPO/CDPSFUNCPOOL017 - Cannot perform function on different resources simultaneously ?

  The SAP error message /SAPAPO/CDPSFUNCPOOL017 indicates that there is an attempt to perform a function on different resources simultaneously in the SAP Advanced Planning and Optimization (APO) module. This error typically arises in scenarios where multiple processes or transactions are trying to access or modify the same resource at the same time, which is not allowed.
  Cause:
  
  Concurrent Access: The most common cause of this error is that multiple users or processes are trying to access or modify the same resource simultaneously. This can happen in planning scenarios where resources are being allocated or scheduled.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. If one process has locked a resource, other processes trying to access it will encounter this error.
  Configuration Issues: There may be configuration settings that are not properly set up, leading to conflicts when accessing resources.
  
  Solution:
  
  Check for Locks: Use transaction codes like SM12 (to check for locks) to see if there are any active locks on the resources you are trying to access. If you find locks that are no longer needed, you can delete them (with caution).
  Sequential Processing: Ensure that processes that access the same resources are executed sequentially rather than concurrently. This may involve adjusting your planning runs or scheduling.
  Review User Access: Check if multiple users are trying to perform actions on the same resources at the same time. If so, coordinate the actions to avoid conflicts.
  System Configuration: Review the configuration settings in the APO system to ensure that they are set up correctly for resource management and that there are no conflicting settings.
  Error Logs: Check the application logs for more detailed information about the error. This can provide insights into what specific actions were being attempted when the error occurred.
