This error typically arises in scenarios involving the configuration of capabilities, roles, or permissions within the SAP system.
  Cause:
  The error occurs when there is an attempt to assign a capability root to a node that is already designated as a root node. In SAP, a root node is a top-level node in a hierarchy, and it cannot have another root node assigned to it. This can happen due to:
  
  Misconfiguration: The system may have been incorrectly configured, leading to an attempt to assign a capability root to an existing root node.
  Hierarchy Issues: There may be issues with the hierarchy structure where the relationships between nodes are not properly defined.
  Duplicate Assignments: There might be an attempt to assign the same capability root to multiple nodes, which is not allowed.
  
  Solution:
  To resolve the DFS_CAP_COMMON018 error, you can take the following steps:
  
  
  Review Configuration: Check the configuration settings for the capability roots and ensure that they are correctly defined. Make sure that no capability root is being assigned to a root node.
  
  
  Check Hierarchy Structure: Examine the hierarchy of nodes to ensure that the relationships are correctly established. Ensure that each node is assigned appropriately without violating the root node constraints.
  
  
  Remove Duplicate Assignments: If there are duplicate assignments, remove them to ensure that each capability root is assigned to only one node.
  
  
  Consult Documentation: Refer to the SAP documentation or help resources related to the specific module you are working with. This can provide insights into the correct configuration and usage of capability roots.
  
  
  Use Transaction Codes: If applicable, use relevant transaction codes (like SU01 for user management or PFCG for role management) to review and adjust the assignments.
