• What is the cause and solution for SAP error message /SEHS/DG_DG212 - *Intervals &1 (from &2) overlap with predecessor (to &3) ?

  The SAP error message /SEHS/DG_DG212 indicates that there is an overlap in time intervals for a specific data object or process. This typically occurs in scenarios where time-based data is being processed, such as in scheduling, planning, or data management tasks. The error message specifically states that the intervals defined (from &2 to &3) overlap with a predecessor interval (to &3).
  Cause:
  
  
  Overlapping Time Intervals: The most common cause of this error is that the time intervals defined for a particular task or data entry overlap with those of a predecessor task or entry. This can happen if:
  
  Two tasks are scheduled to occur at the same time.
  There is a mistake in the input of the start and end times for the intervals.
  Data was imported or entered incorrectly, leading to conflicting time periods.
  
  
  
  Incorrect Configuration: Sometimes, the configuration settings in the system may not allow overlapping intervals, leading to this error when such overlaps are attempted.
  
  
  Solution:
  
  
  Review Time Intervals: Check the time intervals for the tasks or data entries involved. Ensure that the start and end times do not overlap. Adjust the intervals as necessary to ensure they are sequential rather than overlapping.
  
  
  Adjust Predecessor Tasks: If the predecessor task is causing the overlap, consider adjusting its end time or the start time of the current task to eliminate the conflict.
  
  
  Data Validation: Implement validation checks in your data entry process to prevent overlapping intervals from being entered in the first place.
  
  
  Consult Documentation: Review the relevant SAP documentation or configuration settings related to the specific module you are working with to understand any constraints or rules regarding time intervals.
  
  
  Testing: After making adjustments, test the changes in a development or test environment before applying them to the production system to ensure that the error is resolved.
  
  
  Related Information:

  User Roles and Permissions: Ensure that the user roles and permissions are correctly set up to allow for the necessary changes to be made without causing further issues.
