• What is the cause and solution for SAP error message WL869 - Latest start & & is later than latest end & & ?

  The SAP error message WL869 indicates that there is a scheduling conflict in the worklist or planning process. Specifically, it means that the "latest start" time for a task or operation is later than the "latest end" time, which is logically inconsistent and cannot be processed.
  Cause:
  
  Incorrect Scheduling Parameters: The latest start time may have been set incorrectly, possibly due to manual entry errors or incorrect configuration in the scheduling parameters.
  Dependency Issues: There may be dependencies between tasks that have not been properly accounted for, leading to a situation where one task cannot start because another task has not yet completed.

  Solution:
  
  Review Scheduling Parameters: Check the scheduling parameters for the task or operation in question. Ensure that the latest start and latest end times are set correctly.

  Check Resource Availability: Ensure that the resources required for the task are available and that their availability is correctly reflected in the scheduling.
  Correct Data Entry: If the error is due to incorrect data entry, correct the relevant fields in the planning or scheduling screens.
  Recalculate Schedule: After making the necessary adjustments, recalculate the schedule to ensure that all tasks are aligned correctly.
