• What is the cause and solution for SAP error message /SAPDMC/LSMW_GLO_040021 - Interval overlaps with another interval. ?

  The SAP error message /SAPDMC/LSMW_GLO_040021 indicating "Interval overlaps with another interval" typically occurs in the context of using the Legacy System Migration Workbench (LSMW) in SAP. This error arises when you are trying to define time intervals (for example, in a data migration project) that overlap with existing intervals in the system.
  Cause:
  The error is caused by the following scenarios:
  
  Overlapping Time Intervals: You are trying to create or modify a time interval that overlaps with an existing interval in the same object or context.
  Incorrect Data Entry: There may be a mistake in the data entry where the start and end dates/times of the intervals are not correctly defined, leading to overlaps.
  Configuration Issues: There may be configuration settings in the LSMW project that are not aligned with the existing data.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Intervals: Review the existing intervals in the system to identify any that overlap with the interval you are trying to create or modify. You can do this by navigating to the relevant transaction or report that displays the intervals.
  
  
  Modify the New Interval: Adjust the start and end dates/times of the new interval you are trying to create so that it does not overlap with any existing intervals. Ensure that the new interval is distinct and does not conflict with others.
  
  
  Delete or Adjust Existing Intervals: If the existing intervals are no longer needed or can be adjusted, consider deleting or modifying them to eliminate the overlap.
  
  
  Validation: After making changes, validate the intervals again to ensure that there are no overlaps. This may involve re-running the LSMW project or using the relevant transaction to check for errors.
  
  
  Consult Documentation: If you are unsure about the intervals or the data structure, consult the SAP documentation or help resources related to LSMW and data migration.
