What causes this issue?

The fixed finish date of the project element is before its fixed start
date.

System Response

The system sets the duration of the project element to zero. The system
may calculate the dates incorrectly, for example,
if there are no actual start or finish dates.

How to fix this error?

Correct the fixed start date or the fixed finish date.

• What is the cause and solution for SAP error message DPR_SHARED219 - &1 &2: Start constraint conflicts with fixed finish ?

  The SAP error message DPR_SHARED219 indicates a conflict between a start constraint and a fixed finish date in a project management context, typically within SAP Project System (PS) or SAP Portfolio and Project Management (PPM). This error arises when the scheduling of a task or activity is not feasible due to conflicting constraints.
  Cause:
  
  Start Constraint: A start constraint is a condition that specifies when a task must begin. For example, it may be set to start on a specific date or after the completion of a predecessor task.
  Fixed Finish Date: A fixed finish date is a constraint that specifies when a task must be completed. This means that the task cannot finish later than this date.
  Conflict: The error occurs when the defined start constraint does not allow the task to finish by the fixed finish date. For instance, if a task is set to start after a certain date but also has a fixed finish date that is earlier than the calculated finish date based on the start constraint, a conflict arises.
  
  Solution:
  To resolve the DPR_SHARED219 error, you can take the following steps:
  
  Review Constraints: Check the start and finish constraints of the task in question. Ensure that they are logically consistent and do not conflict with each other.
  Adjust Start Constraint: If the start constraint is too restrictive, consider adjusting it to allow for an earlier start date that aligns with the fixed finish date.
  Modify Fixed Finish Date: If the fixed finish date is not critical, you may consider changing it to accommodate the start constraint.
  Check Dependencies: Review any predecessor or successor relationships that may be influencing the scheduling of the task. Ensure that these relationships are set correctly.
  Recalculate Dates: After making adjustments, recalculate the project dates to ensure that all tasks are scheduled correctly without conflicts.
  
  Related Information:
  
  Project Management Best Practices: Understanding how to effectively manage constraints and dependencies in project scheduling can help prevent such errors.
  SAP Documentation: Refer to SAP's official documentation for detailed information on project scheduling, constraints, and error messages.
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP for project management, such as CJ20N (Project Builder) or CN41 (Project Structure Overview), to help you navigate and resolve issues.
  
  By carefully reviewing and adjusting the constraints, you should be able to resolve the DPR_SHARED219 error and ensure that your project scheduling is accurate and conflict-free.
