• What is the cause and solution for SAP error message CC266 - No date shift (inconsistency in phase) ?

  The SAP error message CC266 "No date shift (inconsistency in phase)" typically occurs in the context of project management, particularly when dealing with project planning and scheduling in SAP's Project System (PS) module. This error indicates that there is an inconsistency in the dates assigned to different phases of a project, which prevents the system from performing a date shift.
  Cause:
  
  
  Inconsistent Dates: The most common cause of this error is that the start and finish dates of different phases or activities in the project do not align correctly. For example, a subsequent phase may have a start date that is earlier than the finish date of a preceding phase.
  
  
  Missing Dependencies: If there are dependencies between tasks or phases that are not properly defined, it can lead to inconsistencies in the scheduling.
  
  
  Incorrect Planning Parameters: The planning parameters set for the project may not allow for the necessary shifts in dates, leading to conflicts.
  
  
  Manual Changes: Manual adjustments to dates or phases that do not respect the logical sequence of the project can also trigger this error.
  
  
  Solution:
  
  
  Check Phase Dates: Review the start and finish dates of all phases and activities in the project. Ensure that they are logically sequenced and that there are no overlaps or inconsistencies.

  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling project scheduling issues.
