How To Fix DPR_SHARED239 - &1 &2: Constraint may cause scheduling problems

DPR_SHARED239 - Overview

• 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.

DPR_SHARED239 - Details

• 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.
