• What is the cause and solution for SAP error message IP429 - Call horizon > 100% is not allowed ?

  The SAP error message IP429 "Call horizon > 100% is not allowed" typically occurs in the context of production planning and scheduling, particularly when dealing with capacity planning in SAP's Integrated Planning (IP) module. This error indicates that the planned capacity utilization exceeds 100%, which is not permissible in the system.
  Cause:
  
  Excessive Demand: The planned production or demand exceeds the available capacity of the resources (work centers, machines, etc.).
  Incorrect Planning Parameters: The planning parameters or settings may not be correctly configured, leading to unrealistic capacity utilization.
  Overlapping Orders: Multiple production orders may be scheduled to run simultaneously on the same resource, causing the total utilization to exceed 100%.
  Capacity Constraints: The capacity of the work center may not be sufficient to handle the planned workload.
  
  Solution:
  
  
  Review Capacity Planning:
  
  Check the capacity of the relevant work centers and ensure that they are correctly defined in the system.
  Adjust the available capacity if necessary, considering factors like shifts, maintenance, and downtime.
  
  
  
  Adjust Production Plans:
  
  Re-evaluate the production plan to ensure that the demand does not exceed the available capacity.
  Consider rescheduling or delaying some production orders to balance the load.
  
  
  
  Modify Planning Parameters:
  
  Review and adjust the planning parameters in the system to ensure they reflect realistic production capabilities and constraints.
  
  
  
  Use Capacity Evaluation Tools:
  
  Utilize SAP's capacity evaluation tools to analyze the load on work centers and identify bottlenecks.
  Use transaction codes like CM01 (Capacity Planning) to visualize and manage capacity utilization.
  
  
  
  Check for Overlapping Orders:
  
  Ensure that there are no overlapping production orders that could be causing the capacity to exceed 100%.
  If necessary, stagger the start times of production orders to avoid conflicts.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidance on capacity planning and the IP module.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CM01 (Capacity Planning), CM21 (Capacity Leveling), and IP01 (Interactive Planning).
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Training and Support: Consider training for users involved in production planning to better understand capacity management and planning processes in SAP.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the IP429 error and ensure that your production planning aligns with available capacity.
