• What is the cause and solution for SAP error message DMEE_PAYMFORMAT399 - Sort field &1 was not defined as a key field ?

  The SAP error message DMEE_PAYMFORMAT399 indicates that a sort field specified in the DMEE (Data Medium Exchange Engine) payment format is not defined as a key field. This error typically arises when configuring payment formats for electronic payments, such as bank transfers or direct debits.
  Cause:
  The error occurs when:
  
  A sort field is referenced in the DMEE tree structure, but it has not been defined as a key field in the relevant node.
  The DMEE configuration expects certain fields to be defined as key fields for sorting purposes, but the configuration does not meet this requirement.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Access DMEE Configuration:
  
  Go to transaction code DMEE in SAP.
  
  
  
  Check the DMEE Tree:
  
  Open the relevant DMEE tree that is causing the error.
  Navigate to the node where the sort field is defined.
  
  
  
  Define Key Fields:
  
  Ensure that the sort field (e.g., &1) is defined as a key field in the node where it is being used.
  To do this, select the node and check the properties. You should see an option to define key fields. Add the sort field as a key field if it is not already included.
  
  
  
  Validate the Configuration:
  
  After making changes, validate the DMEE tree to ensure there are no other errors.
  You can use the "Check" function in the DMEE transaction to validate the configuration.
  
  
  
  Test the Payment Format:
  
  Once the changes are made, test the payment format to ensure that the error no longer occurs and that the payment file is generated correctly.
