• What is the cause and solution for SAP error message DG212 - *Intervals &1 (from &2) overlap with predecessor (to &3) ?

  The SAP error message DG212 indicates that there is an overlap in the time intervals defined for a particular object, such as a project, task, or resource. This error typically occurs in the context of project management or resource planning within SAP, where time intervals must be distinct and non-overlapping to ensure accurate scheduling and resource allocation.
  Cause:
  The error message DG212 arises when:
  
  You are trying to create or modify a time interval (e.g., a task or resource allocation) that overlaps with an existing interval.
  The new interval you are trying to define starts before the existing interval ends or ends after the existing interval starts.
  
  Solution:
  To resolve the DG212 error, you can take the following steps:
  
  
  Review Existing Intervals: Check the existing intervals for the object in question. Identify the intervals that are causing the overlap.
  
  
  Adjust Time Intervals: Modify the start and end times of the new interval you are trying to create or adjust the existing intervals to ensure that they do not overlap. Ensure that the intervals are distinct.
  
  
  Check Dependencies: If the intervals are related to tasks or resources that have dependencies, ensure that the dependencies are correctly defined and that the intervals align with the project timeline.
  
  
  Use the Correct Transaction: Make sure you are using the correct transaction or module in SAP for managing the intervals. Sometimes, using the wrong transaction can lead to confusion regarding the intervals.
  
  
  Consult Documentation: If you are unsure about how to adjust the intervals, refer to the SAP documentation or help resources related to project management or resource planning.
  
  
  Seek Help from SAP Support: If the issue persists and you cannot identify the cause of the overlap, consider reaching out to your SAP support team or consulting SAP notes for further assistance.
  
  
  Related Information:
  
  SAP Modules: This error is commonly encountered in modules such as SAP Project System (PS), SAP Controlling (CO), or SAP Human Capital Management (HCM).
  Transaction Codes: Familiarize yourself with relevant transaction codes that deal with project planning and resource management, such as CJ20N (Project Builder) or CATS (Cross-Application Time Sheet).
  Best Practices: Implement best practices for project scheduling and resource allocation to minimize the chances of overlapping intervals in the future.
  
  By following these steps, you should be able to resolve the DG212 error and ensure that your time intervals are correctly defined within SAP.
