• What is the cause and solution for SAP error message /SAPAPO/PP_OPTIMIZER158 - Production process model/PDS &1: Fixed resource consumption not allowed ?

  The SAP error message /SAPAPO/PP_OPTIMIZER158 indicates that there is an issue with the production process model (PDS) in the context of the SAP Advanced Planning and Optimization (APO) module. Specifically, the error states that "Fixed resource consumption not allowed" for the specified PDS.
  Cause:
  This error typically arises when:
  
  Fixed Resource Consumption: The production process model is configured to use fixed resource consumption, but the settings or the context in which it is being used do not allow for this type of consumption. Fixed resource consumption means that a certain amount of resource is consumed regardless of the quantity produced.
  Incompatibility with Planning: The planning scenario or the specific production order may not support fixed resource consumption due to the way the resources or PDS are defined.
  Configuration Issues: There may be configuration issues in the PDS or the resource settings that prevent the use of fixed resource consumption.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check PDS Configuration:
  
  Go to the PDS in the SAP system and check the settings related to resource consumption. Ensure that the fixed resource consumption is correctly defined and that it is appropriate for the production process you are trying to execute.
  
  
  
  Review Resource Settings:
  
  Check the resource settings in the APO system. Ensure that the resources involved in the PDS are configured to allow fixed consumption if that is the intended use.
  
  
  
  Adjust Planning Parameters:
  
  If the planning scenario does not support fixed resource consumption, consider adjusting the planning parameters or the production process model to use variable resource consumption instead.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation related to the production process model and resource consumption to ensure that you are following the best practices and guidelines.
  
  
  
  Testing:
  
  After making changes, test the PDS and the planning scenario to ensure that the error is resolved and that the production planning can proceed without issues.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists after checking the configuration and settings, consider reaching out to SAP support for further assistance. They may provide insights specific to your system configuration.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on configuring PDS and resource consumption.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/PDS for managing PDS and /SAPAPO/OPTIMIZER for optimizer settings.
  Training and Documentation: Consider training resources or documentation on SAP APO and production planning to better understand the configurations and best practices.
  
  By following these steps, you should be able to identify the root cause of the error and implement a solution to resolve it.
