• What is the cause and solution for SAP error message /SAPAPO/RRP_ATP162 - Compact scheduling may not be used in CTP ?

  The SAP error message /SAPAPO/RRP_ATP162 indicates that compact scheduling cannot be used in the context of Capable-to-Promise (CTP) checks. This error typically arises in the Advanced Planning and Optimization (APO) module when there is an attempt to use compact scheduling in a scenario where CTP is being applied.
  Cause:
  
  
  CTP Configuration: The error is primarily caused by the configuration settings in the APO system. CTP checks are designed to determine whether a product can be produced or delivered based on available resources and constraints. Compact scheduling, which is a method of scheduling that optimizes the use of resources, is not compatible with the CTP process.
  
  
  Planning Strategy: The planning strategy or the settings for the product in question may not support compact scheduling when CTP is active. This can happen if the product is set up in a way that requires detailed scheduling rather than compact scheduling.
  
  
  Resource Constraints: If the resources involved in the production process have constraints that cannot be resolved with compact scheduling, this error may occur.
  
  
  Solution:
  
  
  Review CTP Settings: Check the configuration of the CTP settings in the APO system. Ensure that the settings align with the requirements of the products being planned.
  
  
  Adjust Scheduling Method: If compact scheduling is not necessary for the specific planning scenario, consider switching to a different scheduling method that is compatible with CTP. This may involve changing the planning strategy or the resource settings.
  
  
  Check Product Master Data: Review the product master data to ensure that the settings for the product do not conflict with the use of compact scheduling. This includes checking the planning strategy, production version, and any other relevant parameters.
  
  
  Consult Documentation: Refer to SAP documentation or notes related to CTP and compact scheduling for any specific guidelines or recommendations that may apply to your situation.
  
  
  Engage SAP Support: If the issue persists after reviewing the settings and configurations, consider reaching out to SAP support for further assistance. They may provide insights or patches that can resolve the issue.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide updates to the APO module.
  APO Configuration Guides: Review the configuration guides for APO, particularly those related to CTP and scheduling methods.
  Training and Documentation: Consider training for users involved in APO planning to ensure they understand the implications of different scheduling methods and CTP.
  
  By addressing the configuration and understanding the limitations of compact scheduling in the context of CTP, you can resolve the error and ensure smoother planning processes in SAP APO.
