• What is the cause and solution for SAP error message DMEE459 - Node &1: only atoms can be placed below technical node ?

  The SAP error message DMEE459 indicates that there is an issue with the structure of your DMEE (Data Medium Exchange Engine) format tree. Specifically, the error states that only "atoms" (which are the basic elements or fields) can be placed below a technical node in the DMEE structure. 
  Cause:
  This error typically occurs when you attempt to place a non-atom node (like a group or a section) under a technical node in the DMEE tree. Technical nodes are designed to hold specific data types and can only contain atomic elements, which are the smallest units of data that can be processed.
  Solution:
  To resolve this error, you should:
  
  
  Review the DMEE Structure: Open the DMEE format tree in the DMEE transaction (usually transaction code DMEE) and navigate to the node that is causing the error.
  
  
  Check Node Types: Ensure that any nodes placed under the technical node are indeed atomic nodes. If you have mistakenly placed a group or section node under a technical node, you will need to move it.
  
  
  Adjust the Hierarchy: If you need to include a group or section, you should place it at the appropriate level in the hierarchy, ensuring that it is not directly under a technical node.
  
  
  Validate the Format: After making the necessary adjustments, validate the DMEE format to ensure that there are no further structural issues.
  
  
  Test the Output: Once the structure is corrected, generate the output to confirm that the error has been resolved.
  
  
  Related Information:
  
  DMEE Documentation: Refer to SAP documentation on DMEE for detailed information on how to structure your format trees correctly.
  SAP Notes: Check for any relevant SAP Notes that might provide additional insights or updates related to DMEE errors.
  Community Forums: Consider visiting SAP Community forums or other user groups where similar issues may have been discussed.
  
  By following these steps, you should be able to resolve the DMEE459 error and ensure that your DMEE format is correctly structured.
