• What is the cause and solution for SAP error message DMU123 - Node &1 will be deleted the next time you save ?

  The SAP error message DMU123 indicates that a node (which could be a data object, a structure, or a component in a data model) is marked for deletion in the Data Modeler (DMU) and will be removed the next time you save your changes. This message typically arises in the context of data modeling or data management tasks within SAP systems.
  Cause:
  
  Manual Deletion: The node was manually marked for deletion by the user.
  Data Model Changes: Changes in the data model that require certain nodes to be removed due to dependencies or restructuring.
  Inconsistent Data: The node may be inconsistent with the current data model or may have been flagged for deletion due to validation checks.
  
  Solution:
  
  Review Changes: Check the changes made to the data model to understand why the node is marked for deletion. If the deletion was unintentional, you can restore the node.
  Undo Deletion: If you want to keep the node, you can typically right-click on the node in the Data Modeler and select an option to undo the deletion or restore it.
  Save Changes: If you are sure that the deletion is intended, you can proceed to save your changes, which will permanently remove the node from the data model.
  Check Dependencies: Ensure that there are no dependencies or references to the node that might affect other parts of the data model.
  
  Related Information:
  
  Documentation: Refer to SAP documentation for the specific module you are working with, as the context of the error may vary based on the application (e.g., SAP BW, SAP HANA).
  Transaction Codes: Familiarize yourself with relevant transaction codes that may help in managing data models, such as RSA1 for SAP BW or HANA Studio for SAP HANA.
  Support: If the issue persists or if you are unsure about the implications of deleting the node, consider reaching out to your SAP support team or consulting the SAP Community for further assistance.
