• What is the cause and solution for SAP error message SPC02814 - Unit '&' from the IDoc differs from unit '&' from Purchase Order '&' ?

  The SAP error message SPC02814 indicates a mismatch between the unit of measure (UoM) specified in an IDoc and the unit of measure defined in the corresponding Purchase Order (PO). This error typically occurs during the processing of IDocs related to purchasing documents, such as when receiving goods or processing invoices.
  Cause:
  The error arises when:
  
  The unit of measure in the IDoc does not match the unit of measure in the Purchase Order.
  There may be a configuration issue where the units of measure are not properly defined or mapped.
  The IDoc may be generated from a system that uses a different unit of measure than what is defined in SAP for the Purchase Order.
  
  Solution:
  To resolve the SPC02814 error, you can take the following steps:
  
  
  Check the IDoc Data:
  
  Review the IDoc data to identify the unit of measure being sent. You can use transaction WE02 or WE19 to analyze the IDoc.
  Ensure that the unit of measure in the IDoc matches the unit of measure in the Purchase Order.
  
  
  
  Verify Purchase Order Details:
  
  Access the Purchase Order in SAP using transaction ME23N and check the unit of measure defined for the relevant line item.
  Ensure that the unit of measure in the Purchase Order is correct and corresponds to what is expected.
  
  
  
  Mapping Configuration:
  
  If the IDoc is generated from an external system, check the mapping configuration between the external system and SAP. Ensure that the units of measure are correctly mapped.
  If necessary, update the mapping to ensure consistency.
  
  
  
  Unit of Measure Conversion:
  
  If the IDoc is using a different unit of measure that is valid but not the same as the Purchase Order, consider implementing a conversion logic if applicable.
  Ensure that the conversion factors are correctly defined in the system.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP Basis or functional team for any specific configurations related to units of measure.
  
  
  
  Testing:
  
  After making the necessary changes, test the IDoc processing again to ensure that the error is resolved.
