How To Fix DPR_SHARED203 - &1 &2: Start constraint conflicts with duration

SAP Error Message - Details

• Message type: E = Error

• Message class: DPR_SHARED - Development Projects: Messages for Shared Objects

• Message number: 203

• Message text: &1 &2: Start constraint conflicts with duration

What causes this issue?

The system calculated a start date from the finish date and duration
when scheduling the project element. This start date conflicts with the
start date of the start constraint.

System Response

The system sets the start date of the start constraint as the calculated
start of the project element and recalculates the finish date for the
project element from the duration as necessary.

How to fix this error?

Check whether the start constraint of the project element is realistic.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message DPR_SHARED203 - &1 &2: Start constraint conflicts with duration ?

  The SAP error message DPR_SHARED203 typically occurs in the context of project management within SAP, particularly when dealing with project planning and scheduling in the SAP Project System (PS) or SAP Portfolio and Project Management (PPM) modules. This error indicates that there is a conflict between the start constraint of a task and its duration, which prevents the task from being scheduled correctly.
  Cause:
  The error arises when:
  
  Start Constraint: A task has a defined start constraint (e.g., "Must Start On," "Start No Earlier Than," or "Start No Later Than") that conflicts with the task's duration.
  Duration: The duration of the task is such that, given the start constraint, it cannot be completed within the allowed time frame.
  Dependencies: There may be dependencies with other tasks that further complicate the scheduling.
  Resource Availability: Resource constraints may also play a role, where the resources required for the task are not available during the scheduled time.
  
  Solution:
  To resolve the DPR_SHARED203 error, you can take the following steps:
  
  
  Review Task Constraints:
  
  Check the start constraints set for the task. If the constraint is too restrictive, consider modifying it to allow for more flexibility.
  
  
  
  Adjust Task Duration:
  
  Review the duration of the task. If it is set too long in relation to the start constraint, consider reducing the duration if feasible.
  
  
  
  Check Dependencies:
  
  Examine any predecessor or successor relationships with other tasks. Ensure that the scheduling of these tasks does not conflict with the task in question.
  
  
  
  Resource Allocation:
  
  Verify that the resources assigned to the task are available during the planned start and duration. Adjust resource assignments if necessary.
  
  
  
  Re-schedule the Task:
  
  If changes are made to constraints, duration, or dependencies, re-schedule the task to see if the error persists.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on managing task constraints and scheduling in your version of SAP.
  
  
  
  Related Information:
