SAP Error Message - Details

• Message type: E = Error

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

• Message number: 239

• Message text: &1 &2: Constraint may cause scheduling problems

What causes this issue?

You have set a constraint on &V1& &V2& and this project element has
lower-level project elements, for example, you have set a constraint on
a phase which has lower-level tasks.
You have specified <LS>bottom-up scheduling</> for the project by means
of the project type.
In this type of scheduling, the dates of the superior project elements
are defined by the dates of the lower-level project elements, that is,
the dates of a phase are specified by the dates of the lower-level
tasks.
Therefore, it is not advisable to set a constraint of this kind on &V1&
&V2& in this type of scheduling.

System Response

The constraint remains.

How to fix this error?

Check the constraint. Set a corresponding constraint on the lower-level
project elements instead.

• What is the cause and solution for SAP error message DPR_SHARED239 - &1 &2: Constraint may cause scheduling problems ?

  The SAP error message DPR_SHARED239 indicates that there is a constraint in the project scheduling that may lead to scheduling problems. This error typically arises in the context of project management within SAP, particularly when using the SAP Project System (PS) or SAP Portfolio and Project Management (PPM) modules.
  Cause:
  The error message DPR_SHARED239 is usually triggered by one or more of the following reasons:
  
  
  Resource Constraints: There may be insufficient resources (e.g., personnel, equipment) allocated to the project, leading to potential delays in task completion.
  
  
  Dependency Conflicts: Tasks may have conflicting dependencies that prevent them from being scheduled properly. For example, a task may be set to start before its predecessor has finished.
  
  
  Time Constraints: There may be time constraints (e.g., deadlines) that are not aligned with the available scheduling options, causing conflicts in the project timeline.
  
  
  Overlapping Tasks: Tasks that are scheduled to occur simultaneously may exceed the available resources, leading to scheduling issues.
  
  
  Incorrect Dates: Start and finish dates for tasks may be incorrectly set, causing conflicts in the project schedule.
  
  
  Solution:
  To resolve the DPR_SHARED239 error, consider the following steps:
  
  
  Review Resource Allocation: Check the resource assignments for the project and ensure that there are enough resources available to meet the project demands. Adjust resource allocations as necessary.
  
  
  Examine Task Dependencies: Review the dependencies between tasks to ensure they are correctly defined. Adjust the sequence of tasks if necessary to eliminate conflicts.
  
  
  Adjust Time Constraints: If there are time constraints that are causing issues, consider adjusting them to allow for more flexibility in scheduling.
  
  
  Reassess Task Scheduling: Look for overlapping tasks and adjust their schedules to ensure that they do not conflict with each other. This may involve rescheduling some tasks to different time slots.
  
  
  Check Dates: Verify that the start and finish dates for all tasks are set correctly and are realistic given the project timeline.
  
  
  Use Scheduling Tools: Utilize SAP's scheduling tools and features to analyze the project schedule and identify potential issues. The Gantt chart or network diagram can be helpful in visualizing task relationships and resource allocation.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling scheduling issues within the context of your project.
