  Missing or invalid data in task list components or operations.
  Errors during creation, change, or display of hierarchical task lists.
  System inconsistencies or data corruption in task list tables (e.g., PLKO, PLPO).
  Incorrect usage of task list hierarchy functions or transactions.

  a) Analyze the specific message number and text
  
  Each message number (001 to 049) corresponds to a specific issue. Check the exact message text to understand the precise problem.

  Use transaction IA05 (Display Task List) or IA06 (Change Task List) to review the task list and its hierarchy.
  Verify that all parent and child operations are correctly linked.
  Ensure that all required fields are filled and consistent.
  
  c) Correct the hierarchy
  
  If the hierarchy is incorrect, adjust the parent-child relationships.
  Delete or recreate problematic operations or sub-operations if necessary.
  
  d) Use SAP standard tools
  
  Run consistency checks or repair tools if available.
  Use transaction IA07 (Task List Consistency Check) to identify and fix inconsistencies.
