  The SAP error message /SAPAPO/MAT191 indicates that there is no forward consumption period defined when attempting to perform backward consumption in the Advanced Planning and Optimization (APO) module. This error typically arises in the context of demand planning and supply chain management when the system is trying to process consumption of planned orders or forecasts.
  Cause:
  
  Configuration Issue: The error usually occurs when the configuration for consumption settings in the APO system is not properly set up. Specifically, it indicates that the system is trying to apply backward consumption but does not have a defined forward consumption period.
  Master Data Settings: The material master data or the planning book settings may not have the necessary parameters defined for consumption.
  Planning Version: The planning version being used may not have the correct settings for consumption.
  
  Solution:
  
  
  Check Consumption Settings:
  
  Go to the transaction code /SAPAPO/MC62 to check the consumption settings for the relevant planning book.
  Ensure that both forward and backward consumption periods are defined correctly.
  
  
  
  Adjust Material Master Data:

  Review Planning Version:
  
  Ensure that the planning version you are using has the correct settings for consumption. You can check this in the transaction /SAPAPO/MC62 or by reviewing the planning version settings in the configuration.
  
  
  
  Consult Documentation:
