• What is the cause and solution for SAP error message STC_TM003 - Task '&1' requires successor '&2' which is missing or on wrong position ?

  The SAP error message STC_TM003 indicates that there is a problem with the task dependencies in a task chain. Specifically, it means that a task (denoted as '&1') requires a successor task (denoted as '&2') that is either missing or not positioned correctly in the sequence of tasks.
  Cause:
  
  Missing Successor Task: The successor task that is required for the execution of the current task is not defined in the task chain.
  Incorrect Positioning: The successor task is defined but is not in the correct sequence. This could mean that it is placed before the current task or is not linked properly.
  Task Chain Configuration: There may be an issue with how the task chain is configured, leading to incorrect dependencies.
  
  Solution:
  
  
  Check Task Chain Configuration:
  
  Go to the task chain in the SAP system and review the configuration.
  Ensure that the successor task is defined and correctly linked to the current task.
  
  
  
  Add Missing Successor Task:

  Make sure to define the correct dependencies between tasks.
  
  
  
  Rearrange Task Order:
  
  If the successor task is present but in the wrong position, rearrange the tasks in the task chain to ensure that the successor task follows the current task.
  
  
  
  Validate Task Chain:
  
  After making changes, validate the task chain to ensure that all dependencies are correctly set up.
  You can use transaction codes like ST22 or SM37 to check for any additional errors or logs related to the task execution.
  
  
  
  Test the Task Chain:
