  Cause:
  This warning message occurs when the system tries to reference a Material Group 1 (also known as Material Group or Material Group 1) that is not defined in the system. Material groups are used to classify materials for reporting, pricing, and other business processes.
  
  The material master record or a transaction is referring to a material group code that does not exist in the customizing table.
  The material group might have been deleted or never created.
  The material group entered in the transaction or master data is incorrect or mistyped.
  
  
  Where is Material Group 1 maintained?
  Material Group 1 is maintained in the customizing table T023 (Material Groups).
  
  Solution:
  
  
  Check the Material Group 1 value:
  
  Verify the material group code entered in the material master or transaction.
  Go to the material master (MM03) and check the material group field.

  Create or maintain the missing Material Group:
  
  If the material group does not exist, create it via customizing:
  
  SPRO ? Logistics - General ? Material Master ? Basic Settings ? Material Groups ? Define Material Groups
  
  
  Or use transaction OMS2 to maintain material groups.
  
  
  
  Correct the material group in the material master or transaction:
  
  If the material group is incorrect, update it with a valid material group.
