• What is the cause and solution for SAP error message /SAPAPO/SEQ021 - No capacity available ?

  The SAP error message /SAPAPO/SEQ021 No capacity available typically occurs in the context of Advanced Planning and Optimization (APO) when there is an attempt to schedule a production order or a planned order, but the system finds that there is insufficient capacity available in the relevant resources (e.g., work centers, machines, or labor) to meet the demand.
  Causes:
  
  Capacity Constraints: The work center or resource may have reached its maximum capacity, meaning that all available hours are already allocated to other orders.
  Incorrect Capacity Planning: The capacity planning settings may not be configured correctly, leading to an inaccurate representation of available capacity.
  Order Overlap: There may be overlapping orders that are scheduled to use the same resource at the same time, leading to a conflict.
  Resource Availability: The resource may be marked as unavailable due to maintenance, holidays, or other reasons.
  Incorrect Time Period: The scheduling may be attempted in a time period where the resource is not available.
  
  Solutions:
  
  Check Capacity Availability: Review the capacity of the relevant work centers or resources in the Capacity Planning view. Ensure that there is enough capacity available for the planned production.
  Adjust Production Orders: If possible, adjust the production orders to stagger their start times or change their scheduling to times when capacity is available.
  Modify Capacity Settings: If the capacity settings are incorrect, adjust them in the work center configuration to reflect the actual available capacity.
  Review Resource Allocation: Check for any overlapping orders and reallocate resources as necessary to avoid conflicts.
  Utilize Alternative Resources: If the primary resource is unavailable, consider using alternative resources that can fulfill the production requirements.
  Increase Capacity: If the demand consistently exceeds capacity, consider increasing the capacity of the work center by adding shifts, overtime, or additional resources.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like CM01 (Capacity Planning) or C223 (Work Center) to analyze and adjust capacity settings.
  APO Configuration: Review the configuration settings in APO for capacity planning, including the settings for planning versions and planning books.
  Capacity Evaluation Reports: Utilize reports such as S031 (Capacity Evaluation) to analyze capacity utilization and identify bottlenecks.
  Documentation: Refer to SAP Help documentation for detailed guidance on capacity planning and scheduling in APO.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the /SAPAPO/SEQ021 No capacity available error and successfully schedule your production orders.
