• What is the cause and solution for SAP error message CN879 - Order unit does not correspond with unit from info record ?

  The SAP error message CN879 ("Order unit does not correspond with unit from info record") typically occurs in the context of purchasing and procurement processes when there is a mismatch between the unit of measure specified in a purchase order and the unit of measure defined in the info record for the material.
  Cause:
  
  
  Unit of Measure Mismatch: The most common cause of this error is that the unit of measure (UoM) used in the purchase order does not match the unit of measure defined in the info record for the material. For example, if the info record specifies that the material is to be ordered in "KG" but the purchase order specifies "LB", this error will occur.
  
  
  Incorrect Info Record Setup: The info record may not have been set up correctly, or it may have been changed after the purchase order was created.
  
  
  Material Master Settings: The material master data may also have inconsistent unit of measure settings that do not align with the info record.
  
  
  Solution:
  
  
  Check the Info Record: 
  
  Go to the transaction code ME13 (Display Info Record) and check the unit of measure defined for the material in the info record. Ensure that it matches the unit of measure used in the purchase order.
  
  
  
  Adjust the Purchase Order:
  
  If the info record is correct, you may need to adjust the purchase order to use the correct unit of measure. You can do this by going to the transaction code ME22N (Change Purchase Order) and modifying the UoM to match the info record.
  
  
  
  Update the Info Record:
  
  If the purchase order is correct and the info record is not, you may need to update the info record to include the correct unit of measure. Use transaction code ME11 (Create Info Record) or ME12 (Change Info Record) to make the necessary adjustments.
  
  
  
  Check Material Master:
  
  Ensure that the material master data is set up correctly. You can check this using transaction code MM03 (Display Material) and verify the units of measure in the Basic Data and Purchasing views.
  
  
  
  Consult with Procurement Team: If you are unsure about the correct unit of measure to use, consult with your procurement or materials management team to ensure compliance with purchasing policies.
