How To Fix DPR_SHARED858 - Phase &1: Phase type requires sequential phase processing

DPR_SHARED858 - Overview

• Message type: E = Error

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

• Message number: 858

• Message text: Phase &1: Phase type requires sequential phase processing

What causes this issue?

Due to its phase type, phase &V1& must be approved before its successor
phase can be released. For this reason, the phases need to be released
according to the sequence defined in the project structure. You
therefore cannot switch to non-sequential phase processing.

System Response

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

How to fix this error?

If you want to use non-sequential phase processing, assign a phase type
to phase &V1& that does not require phase &V1& to be approved before its
successor phase can been released.

DPR_SHARED858 - Details

• The SAP error message DPR_SHARED858, which states "Phase &1: Phase type requires sequential phase processing," typically occurs in the context of project management within SAP, particularly when dealing with project phases in the Project System (PS) or Project Management (PM) modules. This error indicates that the phase you are trying to process has a dependency that requires it to be executed in a specific sequence.
  
  Cause:
  
  Phase Dependency: The phase you are trying to execute is defined in such a way that it cannot be processed in parallel with other phases. This is often due to dependencies set in the project structure.
  Incorrect Phase Configuration: The configuration of the project phases may not allow for the current phase to be executed until previous phases are completed.
  Project Type Restrictions: Certain project types may have restrictions on how phases can be processed, requiring them to be executed in a specific order.
  
  
  Solution:
  
  Check Phase Dependencies: Review the
