• What is the cause and solution for SAP error message RSH_LEVELING012 - To dispatch operations, you must schedule them first. ?

  The SAP error message RSH_LEVELING012 indicates that there are operations in a production order or a project that need to be scheduled before they can be dispatched. This error typically occurs in the context of production planning and scheduling within SAP, particularly when using the Capacity Planning or Production Order Management modules.
  Cause:
  The primary cause of this error is that the operations you are trying to dispatch have not been scheduled yet. In SAP, scheduling is a prerequisite for dispatching operations, as it determines the start and finish times for the operations based on available resources and capacities.
  Solution:
  To resolve this error, you need to ensure that the operations are scheduled before attempting to dispatch them. Here are the steps you can follow:
  
  
  Schedule the Operations:
  
  Go to the relevant transaction for scheduling (e.g., CO02 for production orders).
  Select the production order that contains the operations you want to schedule.
  Use the scheduling function (usually found in the menu or as a button) to schedule the operations. This may involve setting the start and finish dates/times based on resource availability.
  
  
  
  Check Scheduling Parameters:
  
  Ensure that the scheduling parameters (like lead times, working times, and resource availability) are correctly set up in the system. Incorrect parameters can lead to scheduling issues.
  
  
  
  Review Capacity Planning:
  
  Check the capacity planning for the work centers involved. If there are capacity constraints, you may need to adjust the production schedule or resource allocation.
  
  
  
  Recheck the Order Status:
  
  After scheduling, verify the status of the production order. It should be in a state that allows for dispatching (e.g., "Scheduled" or "Released").
  
  
  
  Use the Correct Transaction:
  
  Make sure you are using the correct transaction codes for scheduling and dispatching. For example, CO02 for production orders, or the appropriate transaction for project management.
