How To Fix DPR_SHARED211 - &1 &2: Start constraint conflicts with determined start

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 211

• Message text: &1 &2: Start constraint conflicts with determined start

What causes this issue?

A constraint is set for the start of the project element. In forward
scheduling, the system calculates the start (earliest start) of the
project element step by step:
Actual start of the project element (you can use the BAdI to ignore
this)
If no actual start has been set, the system determines it from the
predecessor relationships of the project element.
If no start was found in the previous steps, the system takes the start
of the higher-level project element.
The system then compares the determined start (earliest start) with the
constraint for the start. The warning appears if the start conflicts
with the constraint for the start.

System Response

The system sets the start of the constraint as the calculated start.

How to fix this error?

Check whether the constraint for the start is realistic.

• What is the cause and solution for SAP error message DPR_SHARED211 - &1 &2: Start constraint conflicts with determined start ?

  The SAP error message DPR_SHARED211 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). This error indicates that there is a conflict between the start constraint of a task and the determined start date based on the project scheduling logic.
  
  Cause:
  The error message DPR_SHARED211 is triggered when:
  
  Start Constraint Conflict: The task has a defined start constraint (e.g., "Must Start On," "Start No Earlier Than," or "Start No Later Than") that conflicts with the calculated start date based on dependencies, resource availability, or other scheduling rules.
  Dependency Issues: There may be predecessor or successor relationships that dictate a different start date than what is allowed by the constraints.
  Resource Allocation: If resources are not available at the determined start date, it can lead to a conflict with the constraints set for the
