• What is the cause and solution for SAP error message /SAPAPO/CTM1535 - Resource &1 has buckets with length 0 ?

  The SAP error message /SAPAPO/CTM1535 Resource &1 has buckets with length 0 typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with the Capacity Planning or CTM (Capable-to-Match) functionalities. This error indicates that a resource defined in the system has one or more time buckets with a length of zero, which is not valid for planning purposes.
  Cause:
  
  Zero-Length Buckets: The most common cause of this error is that the resource in question has been defined with time buckets that have a duration of zero. This can happen due to incorrect configuration or data entry errors.
  Resource Configuration: The resource may not have been properly configured in the system, leading to the creation of time buckets that do not have a valid length.
  Planning Version Issues: If the planning version is not set up correctly, it may lead to inconsistencies in the resource definitions.
  
  Solution:
  
  
  Check Resource Configuration:
  
  Go to the resource master data in the SAP APO system.
  Verify the configuration of the resource, particularly the time buckets defined for it.
  Ensure that all time buckets have a valid length greater than zero.
  
  
  
  Adjust Time Buckets:
  
  If you find any time buckets with a length of zero, modify them to have a valid duration. This can typically be done in the resource's planning view or master data settings.
  
  
  
  Review Planning Versions:
  
  Ensure that the planning version you are using is correctly set up and that all necessary data is maintained.
  If necessary, create a new planning version or adjust the existing one to ensure it aligns with the resource definitions.
  
  
  
  Re-run Planning:
  
  After making the necessary adjustments, re-run the planning process to see if the error persists.
  
  
  
  Consult Documentation:
  
  If the issue continues, refer to SAP documentation or consult with your SAP support team for further troubleshooting steps.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like /SAPAPO/CTM for CTM settings or /SAPAPO/RRP3 for resource planning views.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional guidance.
  User Exits and BAdIs: If custom logic is implemented, ensure that it does not inadvertently create zero-length buckets.
