• What is the cause and solution for SAP error message C7070 - Relationship: Maximum duration could not be kept ?

  The SAP error message C7070, which states "Relationship: Maximum duration could not be kept," typically occurs in the context of project management or production planning within SAP. This error indicates that the maximum duration defined for a relationship between tasks or activities in a project cannot be maintained due to scheduling constraints or conflicts.
  Cause:
  
  Scheduling Conflicts: The planned start and finish dates of tasks may conflict with the defined maximum duration for the relationship.
  Resource Constraints: Limited availability of resources (e.g., personnel, equipment) can lead to delays that exceed the maximum duration.
  Incorrect Relationship Definition: The relationships (dependencies) between tasks may not be correctly defined, leading to unrealistic scheduling.
  Changes in Task Duration: If the duration of a predecessor task is extended, it may push the successor task beyond the maximum allowable duration.
  
  Solution:
  
  Review Task Relationships: Check the relationships between tasks to ensure they are correctly defined. Adjust the dependencies if necessary.
  Adjust Maximum Duration: If the maximum duration is too restrictive, consider increasing it to accommodate the actual scheduling needs.
  Resource Allocation: Ensure that resources are adequately allocated to tasks to prevent delays. This may involve reassigning resources or adjusting schedules.
  Re-schedule Tasks: If possible, re-schedule the tasks to ensure that they can be completed within the defined maximum duration.
  Check for Overlapping Tasks: Ensure that there are no overlapping tasks that could be causing scheduling conflicts.
