IP401 - Details

• The SAP error message IP401 indicates that a maintenance plan is on hold due to a predecessor task that has not been completed or is still in a "hold" status. This can occur in the context of maintenance planning and scheduling within the SAP system, particularly in the Plant Maintenance (PM) module.
  
  Cause:
  
  Predecessor Task on Hold: The predecessor task (identified by the call number) is still on hold, which prevents the maintenance plan from being executed.
  Incomplete Tasks: There may be tasks that need to be completed before the current maintenance plan can proceed.
  Scheduling Issues: The maintenance plan may be scheduled to start only after the predecessor task is completed, and if that task is on hold, it will block the current plan.
  
  
  Solution:
  
  
  Check Predecessor Task: 
  
  Navigate to the predecessor task using the call number provided in the error message.
  Review the status of the predecessor task to determine why it is on hold.
