• What is the cause and solution for SAP error message CN710 - Maintain both indicator and date for constraint ?

  The SAP error message CN710, which states "Maintain both indicator and date for constraint," typically occurs in the context of project management or network planning within the SAP system, particularly when dealing with constraints in project scheduling.
  Cause:
  This error arises when there is an inconsistency in the way constraints are defined for a project or network activity. Specifically, it indicates that either:
  
  A constraint indicator (such as "Must Start On," "Must Finish On," etc.) is set without a corresponding date.
  A constraint date is provided without a corresponding constraint indicator.
  
  In other words, the system expects both a constraint type (indicator) and a specific date to be defined together for the constraint to be valid.
  Solution:
  To resolve the CN710 error, you should ensure that both the constraint indicator and the constraint date are properly maintained. Here are the steps to do this:
  
  
  Access the Project or Network Activity:
  
  Go to the relevant project or network activity in the SAP system.
  
  
  
  Check Constraints:
  
  Navigate to the "Constraints" section of the activity or project.
  
  
  
  Maintain Both Fields:
  
  Ensure that if you have set a constraint indicator, you also provide a corresponding date.
  Conversely, if you have a date set, make sure that a constraint indicator is also defined.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save your changes.
  
  
  
  Recheck:
  
  Attempt to execute the action that previously triggered the error to confirm that it has been resolved.
