• What is the cause and solution for SAP error message /SAPAPO/SNPOPT158 - Production process model/PDS &1: Fixed resource consumption not allowed ?

  The SAP error message /SAPAPO/SNPOPT158 indicates that there is an issue with the production process model (PDS) in SAP Advanced Planning and Optimization (APO). Specifically, the error states that "Fixed resource consumption not allowed," which typically arises when there is an attempt to use fixed resource consumption in a context where it is not permitted.
  Cause:
  
  
  Fixed Resource Consumption: This error usually occurs when a production process model (PDS) is configured to use fixed resource consumption, but the settings or the context in which it is being used do not allow for it. Fixed resource consumption is a method where a certain amount of resource is consumed regardless of the quantity produced.
  
  
  Configuration Issues: The PDS may not be correctly configured to handle fixed resource consumption. This could be due to missing settings or incorrect parameters in the PDS.
  
  
  Resource Type: The resource type being used may not support fixed consumption. For example, certain resource types may only allow variable consumption.
  
  
  Planning Scenario: The planning scenario or the specific planning run may not be set up to accommodate fixed resource consumption.
  
  
  Solution:
  
  
  Check PDS Configuration: Review the configuration of the production process model (PDS) to ensure that it is set up correctly for fixed resource consumption. This includes checking the resource settings and ensuring that fixed consumption is allowed.
  
  
  Adjust Resource Settings: If fixed resource consumption is not needed, consider changing the resource settings to allow for variable consumption instead. This may involve modifying the resource's consumption type in the PDS.
  
  
  Review Resource Types: Ensure that the resource type being used supports fixed resource consumption. If it does not, you may need to change the resource type or adjust the PDS accordingly.
  
  
  Planning Parameters: Check the planning parameters and settings in the planning book or the planning run to ensure that they are compatible with fixed resource consumption.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on configuring PDS and resource consumption settings.
  
  
  Testing: After making changes, perform a test run to ensure that the error is resolved and that the production planning process works as expected.
