• What is the cause and solution for SAP error message FL704 - Function groups beginning with 'Y' or 'Z' are reserved for customers ?

  The SAP error message FL704 indicates that you are trying to create or modify a function group that begins with 'Y' or 'Z'. In SAP, function groups that start with these letters are reserved for customer-specific developments. This is a standard practice in SAP to ensure that customer modifications do not interfere with standard SAP functionality.
  Cause:
  
  Function Group Naming Convention: SAP reserves function groups starting with 'Y' or 'Z' for customer use. If you attempt to create or modify a function group with a name that starts with these letters, you will encounter this error.
  System Configuration: The system is configured to prevent the creation of function groups that do not adhere to the naming conventions.
  
  Solution:
  
  Use Appropriate Naming: If you are trying to create a new function group, ensure that the name you are using starts with 'Y' or 'Z'. For example, you can name your function group Y_MY_FUNCTION_GROUP.
  Check Existing Function Groups: If you are trying to modify an existing function group, ensure that you are not trying to change the name to something that starts with 'Y' or 'Z' if it is already reserved.
  Consult Documentation: Review SAP documentation or guidelines regarding naming conventions for function groups and other development objects.
  Authorization: Ensure that you have the necessary authorizations to create or modify function groups in the SAP system.
