This error indicates that the system is unable to release or free a memory container that is no longer needed. Here are some potential causes, solutions, and related information for this error:
  Causes:
  
  Memory Management Issues: The error may arise due to improper handling of memory allocation and deallocation in ABAP programs.

  Debugging: Use the ABAP debugger to step through the code and identify where the error occurs. This can help pinpoint the exact line of code causing the issue.
  Avoid Double Freeing: Implement checks to ensure that a container is not freed multiple times. You can use flags or status indicators to track the state of the container.
  Review Nested Structures: If you are using nested internal tables or structures, ensure that you are managing their lifecycles correctly.
