How To Fix DMEE678 - Node &1 has been removed

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 678

• Message text: Node &1 has been removed

What causes this issue?

Node has been removed from the Child tree.

System Response

The &V1& node was deleted from the Child tree as a step of the
Synchronization process. The reason is one of these:
a) The node was deleted from the Parent tree
b) The node was created in the Child tree under a node, which was
deleted from the Parent tree

How to fix this error?

If you want to restore the deleted node:
1) Display the "Child version before synchronization" in the left pane
2) Click on the deleted node in the Synchronization log - the deleted
node will be selected in the left tree (it does not exist in the right
tree)
3) Use the context menu to copy the node from the left tree and insert
it to the right tree. If the restored node was a Child node, the node
will have the same ID in both trees. If the restored node was parent
node, it will have a new ID in the Child tree, so the parallel
navigation cannot be used.

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.
