• What is the cause and solution for SAP error message FCC1470 - Task cannot start earlier than predecessor task with task ID &1 ?

  The SAP error message FCC1470 indicates that a task in a project cannot start before its predecessor task has been completed. This is a common issue in project management within SAP, particularly when using the Project System (PS) module or similar functionalities that involve task dependencies.
  Cause:
  The error occurs due to the following reasons:
  
  Task Dependencies: The task you are trying to start has a defined predecessor task that must be completed first. This is a part of the project scheduling logic.
  Scheduling Settings: The scheduling settings may not allow for overlapping tasks, or the start date of the task you are trying to initiate is set before the end date of its predecessor.
  Incorrect Dates: The dates assigned to the tasks may be incorrectly configured, leading to conflicts in the scheduling.
  
  Solution:
  To resolve the FCC1470 error, you can take the following steps:
  
  
  Check Task Dependencies:
  
  Review the predecessor and successor relationships in the project. Ensure that the predecessor task is completed before starting the current task.
  You can do this by navigating to the project structure and checking the task relationships.
  
  
  
  Adjust Task Dates:
  
  If the predecessor task is completed, ensure that the start date of the current task is set correctly. You may need to adjust the start date to be after the completion date of the predecessor task.
  You can modify the dates in the task details screen.
  
  
  
  Re-schedule the Project:
  
  If there are multiple tasks with dependencies, consider re-scheduling the entire project to ensure that all tasks are aligned correctly.
  Use the scheduling functions in SAP to automatically adjust the dates based on the dependencies.
  
  
  
  Review Scheduling Parameters:
  
  Check the project settings and parameters related to scheduling. Ensure that they allow for the desired task flow and dependencies.
  
  
  
  Consult Documentation:
  
  If you are unsure about how to adjust the settings or dependencies, refer to the SAP documentation or help resources for guidance on managing task dependencies.
  
  
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like CJ20N (Project Builder) or CJ02 (Change Project) to view and modify project tasks and their dependencies.
  Project Management Best Practices: Familiarize yourself with project management principles, especially regarding task dependencies and scheduling, to avoid similar issues in the future.
  SAP Notes: Check for any relevant SAP Notes or updates that might address specific issues related to task scheduling and dependencies.
  
  By following these steps, you should be able to resolve the FCC1470 error and successfully manage your project tasks in SAP.
