• What is the cause and solution for SAP error message DMEE687 - Node &1 has been redefined; it will not be deactivated ?

  The SAP error message DMEE687 indicates that a node in the Data Medium Exchange Engine (DMEE) has been redefined, and as a result, it cannot be deactivated. This typically occurs when you attempt to deactivate a node that has been modified or redefined in a way that conflicts with its current state.
  Cause:
  
  Redefinition of Nodes: The node you are trying to deactivate has been redefined in the DMEE structure. This means that the node has been altered or has dependencies that prevent it from being deactivated.
  Dependencies: Other nodes or configurations may depend on the node you are trying to deactivate, which can lead to this error.
  Versioning Issues: If you are working with different versions of the DMEE tree, there may be inconsistencies that lead to this error.
  
  Solution:
  
  Check Node Redefinition: Review the DMEE tree structure to identify if the node has been redefined. You can do this by navigating to the DMEE transaction (usually transaction code DMEE) and examining the node properties.
  Remove Redefinition: If the node has been redefined and you do not need the redefinition, consider reverting the node to its original state or removing the redefinition.
  Check Dependencies: Investigate if other nodes or configurations depend on the node you are trying to deactivate. If there are dependencies, you may need to address those first before deactivating the node.
  Consult Documentation: Refer to SAP documentation or notes related to DMEE for any specific guidelines or updates that may pertain to your version of SAP.
  Testing: After making changes, test the DMEE configuration to ensure that it works as expected without the deactivated node.
