• What is the cause and solution for SAP error message GHO_NET074 - Link &1: Object '&2' is already used in Cluster '&3' ?

  The SAP error message GHO_NET074 indicates that there is an issue with the network object being used in a cluster. Specifically, it means that the object you are trying to link or use is already associated with another cluster, which prevents it from being linked to the current one.
  Cause:
  
  Object Already Linked: The object (e.g., a network, node, or other entity) you are trying to link is already part of another cluster.
  Data Integrity: SAP enforces data integrity rules to prevent the same object from being used in multiple clusters simultaneously, which could lead to inconsistencies.
  
  Solution:
  
  Check Existing Links: Verify which cluster the object is currently linked to. You can do this by navigating to the relevant transaction in SAP (e.g., using transaction codes like CNO1 for network objects).
  Remove Existing Link: If you need to link the object to a new cluster, you may need to first unlink it from the existing cluster. This can typically be done through the same transaction where you manage the cluster.
  Create a New Object: If the object must remain in the original cluster, consider creating a new object that can be linked to the desired cluster instead of trying to reuse the existing one.
  Consult Documentation: Review SAP documentation or help resources for specific instructions related to the type of object you are working with, as the steps may vary based on the object type.
