• What is the cause and solution for SAP error message FDT_CORE097 - Function name &1 already used in application within SAP dev. landscape ?

  The SAP error message FDT_CORE097 indicates that a function name you are trying to use in your application is already in use within the SAP development landscape. This typically occurs in the context of using the SAP Fiori Design Time (FDT) or when developing custom applications that involve function modules, methods, or other callable entities.
  Cause:
  
  
  Duplicate Function Name: The function name you are trying to create or use is already defined in the system. This can happen if:
  
  You are trying to create a new function with the same name as an existing one.
  There is a naming conflict due to the use of standard SAP function names or other custom functions.
  
  
  
  Namespace Issues: If you are working in a shared development environment, it is possible that another developer has already created a function with the same name.
  
  
  Solution:
  
  
  Check Existing Functions: 
  
  Use transaction codes like SE37 (Function Modules) or SE80 (Object Navigator) to search for the existing function name. 
  If you find a function with the same name, consider using that function instead of creating a new one.
  
  
  
  Rename Your Function: 
  
  If the existing function is not relevant to your work, consider renaming your function to something unique. Ensure that the new name follows the naming conventions and is descriptive of its purpose.
  
  
  
  Use a Unique Namespace: 
  
  If you are developing custom applications, consider using a unique namespace for your functions to avoid conflicts with standard SAP functions or other custom functions.
  
  
  
  Consult with Team Members: 
  
  If you are in a collaborative environment, check with your team members to see if someone else is using the same function name or if there are any guidelines for naming conventions.
