  Solution:
  
  Use a Unique Key: The simplest solution is to define a new, unique key for the BRF or BRFplus rule you are trying to create. Ensure that the key does not conflict with any existing keys in the system.
  Check Existing Rules: Before creating a new rule, check the existing rules in the BRFplus application to see if the key you want to use is already in use. You can do this by navigating to the relevant BRFplus workbench and searching for the key.
  Modify Existing Rule: If you intended to modify an existing rule, you can do so instead of creating a new one. This will help avoid the duplication issue.
  Consult Documentation: If you are unsure about the key naming conventions or how to manage keys in BRFplus, refer to the SAP documentation or help resources for guidance.
  
  Related Information:
  
  BRFplus Workbench: You can access the BRFplus workbench through transaction code BRF+ in SAP. This tool allows you to manage rules, including creating, modifying, and deleting them.
  Key Naming Conventions: It is a good practice to establish a naming convention for keys to avoid conflicts in the future. This can include prefixes, suffixes, or a structured format that makes keys easily identifiable.
  Error Handling: If you encounter this error frequently, consider implementing error handling or validation checks in your processes to ensure that keys are unique before attempting to create new rules.
  
  By following these steps, you should be able to resolve the FMCA_BRFPLUS316 error and successfully create or manage your BRFplus rules.
