MD122 - Details

• The SAP error message MD122, which states "You have not yet allocated any plants," typically occurs in the context of Material Requirements Planning (MRP) when you are trying to run MRP for a material or a group of materials, but no plants have been assigned to the relevant MRP area or the material master record.
  
  Cause:
  
  Missing Plant Assignment: The material master record does not have any plants assigned to it. This can happen if the material has not been created or maintained properly.
  MRP Area Configuration: If you are using MRP areas, the specific MRP area may not have any plants assigned.
  Incorrect MRP Type: The MRP type for the material may not be set up correctly, leading to the system not recognizing any plants for MRP processing.
  
  
  Solution:
  
  
  Check Material Master:
  
  Go to transaction code MM03 (Display Material) and enter the material number.
  Check the "Plant Data" views (e.g., Basic Data 1, MRP 1, MRP 2)
