• What is the cause and solution for SAP error message /SAPAPO/PINV066 - Cost.func. &1: Fixed costs must equal lower limit times variable costs ?

  The SAP error message /SAPAPO/PINV066 indicates that there is an inconsistency in the cost structure of a cost function in the Advanced Planning and Optimization (APO) module. Specifically, it states that the fixed costs must equal the lower limit times the variable costs. This error typically arises in the context of planning scenarios where cost functions are defined for production or procurement processes.
  Cause:
  The error is triggered when the fixed costs defined for a cost function do not align with the calculated values based on the variable costs and the lower limit. This can happen due to:
  
  Incorrect Cost Function Configuration: The fixed costs may have been set incorrectly in the cost function configuration.
  Data Entry Errors: There may be mistakes in the input data for variable costs or lower limits.
  Changes in Cost Structure: If there have been recent changes to the cost structure, the fixed costs may not have been updated accordingly.
  Inconsistent Master Data: The master data related to the product or resource may not be consistent with the cost function settings.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review Cost Function Configuration:
  
  Go to the transaction where the cost function is defined (e.g., transaction /SAPAPO/MC90 for cost function maintenance).
  Check the fixed costs, variable costs, and lower limits to ensure they are set correctly.
  
  
  
  Verify Input Data:
  
  Ensure that the variable costs and lower limits are entered correctly in the relevant master data records.
  Check for any recent changes that may have affected these values.
  
  
  
  Adjust Fixed Costs:
  
  If the fixed costs are indeed incorrect, adjust them to match the calculated value (lower limit * variable costs).
  
  
  
  Check Master Data:
  
  Review the master data for the product or resource associated with the cost function to ensure consistency.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for specific guidelines on configuring cost functions in APO.
  
  
  
  Testing:
  
  After making adjustments, test the changes in a development or quality environment before applying them to production.
