• What is the cause and solution for SAP error message MY100 - FIFO valuation has not been defined ?

  The SAP error message MY100, which states "FIFO valuation has not been defined," typically occurs in the context of inventory management and valuation methods in SAP. This error indicates that the system is unable to perform a FIFO (First In, First Out) valuation for materials because the necessary configuration has not been set up.
  Cause:
  
  Missing Configuration: The FIFO valuation method has not been defined for the material in question. This can happen if the material master data is incomplete or if the valuation settings have not been properly configured in the system.
  Material Type: The material type may not support FIFO valuation. Certain material types may have specific valuation methods assigned to them.
  Valuation Area Settings: The valuation area (plant or company code) may not have FIFO defined as a valid valuation method.
  
  Solution:
  To resolve the MY100 error, you can follow these steps:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03).
  Check the accounting view to see if FIFO is selected as the valuation method.
  If it is not defined, you may need to change the valuation method to FIFO.
  
  
  
  Define FIFO Valuation:
  
  Use transaction code OMN1 to access the configuration for inventory valuation.
  Ensure that FIFO is defined for the relevant valuation area and material type.
  If necessary, create or adjust the valuation class to include FIFO.
  
  
  
  Check Valuation Area Settings:
  
  Ensure that the valuation area (plant or company code) is set up to allow FIFO valuation.
  You can check this in the configuration settings under SPRO > Logistics - General > Material Master > Valuation > Define Valuation Area.
  
  
  
  Review Material Type Settings:
  
  Check if the material type allows FIFO valuation. You can do this in the configuration settings under SPRO > Logistics - General > Material Master > Basic Settings > Material Types.
  
  
  
  Consult Documentation: If you are unsure about making changes, consult your SAP documentation or reach out to your SAP support team for guidance.
