How To Fix DMEE689 - Check subtree of node &1; there are redefined nodes

SAP Error Message - Details

• Message type: E = Error

• Message class: DMEE - Messages for Data Medium Exchange Engine

• Message number: 689

• Message text: Check subtree of node &1; there are redefined nodes

What causes this issue?

You have deactivated a node in the parent tree and that node has a
subtree with a redefined node.

System Response

Due to the deactivation of the parent node, the system deactivated the
subtree and the redefined node too.

How to fix this error?

If you want the redefined node to be activated<(>,<)> activate the
deactivated parent node. If you want to have only the redefined node
activated, copy and paste the redefined node to another place and
deactivate the parent node again (we recommend that you use the
<LS>Revert to Original </>button for this purpose).

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message DMEE689 - Check subtree of node &1; there are redefined nodes ?

  The SAP error message DMEE689 indicates that there are redefined nodes in the subtree of a specified node in the Data Medium Exchange Engine (DMEE) configuration. This error typically arises when there are conflicting definitions for nodes in the DMEE tree structure, which can lead to issues in generating the desired output format for data exchange.
  Cause:
  
  
  Redefined Nodes: The error occurs when a node in the DMEE tree has been redefined in a way that conflicts with its parent or sibling nodes. This can happen if:
  
  A node is defined multiple times with different properties.
  There are inconsistencies in the node definitions, such as different data types or attributes.
  
  
  
  Incorrect Configuration: The DMEE configuration may have been altered incorrectly, leading to overlapping or conflicting node definitions.
  
  
  Versioning Issues: If there are multiple versions of the DMEE tree, it may lead to confusion and conflicts in node definitions.
  
  
  Solution:
  
  
  Review the DMEE Tree Structure:
  
  Open the DMEE configuration in transaction code DMEE.
  Navigate to the specified node (indicated by &1 in the error message) and check its subtree for any redefined nodes.
  Ensure that each node is uniquely defined and does not conflict with others.
  
  
  
  Remove or Rename Redefined Nodes:
  
  If you find nodes that are redefined, consider removing or renaming them to eliminate the conflict.
  Ensure that the properties of the nodes are consistent and do not overlap.
  
  
  
  Check for Inheritance:
  
  If nodes are intended to inherit properties from parent nodes, ensure that the inheritance is correctly set up and that there are no conflicting definitions.
  
  
  
  Validate Configuration:
  
  After making changes, validate the DMEE configuration to ensure that there are no further errors.
  Use the "Check" function in the DMEE transaction to identify any remaining issues.
  
  
  
  Documentation and Backup:
  
  Document any changes made to the DMEE configuration for future reference.
  Consider backing up the current configuration before making significant changes.
  
  
  
  Related Information:
  
  Transaction Codes: Use transaction code DMEE to access the Data Medium Exchange Engine configuration.
  SAP Notes: Check SAP Notes related to DMEE for any known issues or updates that may address this error.
  Testing: After resolving the issue, perform tests to ensure that the data output is generated correctly without any further errors.
  
  By following these steps, you should be able to resolve the DMEE689 error and ensure that your DMEE configuration is functioning correctly.
