  The SAP error message RE656 indicates that a function group is not within the customer name range. This typically occurs when you are trying to access or execute a function group that is not allowed for customer modifications or extensions. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Function Group Restrictions: SAP has certain function groups that are reserved for standard SAP use and are not intended for customer modifications. If you attempt to create or modify a function group that falls outside the allowed range, you will encounter this error.
  Naming Conventions: SAP uses specific naming conventions for function groups. Customer-defined function groups usually start with a specific prefix (like Z or Y).

  Check Function Group Name: Verify the name of the function group you are trying to access. Ensure that it starts with the appropriate prefix (Z or Y) if it is meant to be a custom function group.
  Use Customer Namespace: If you need to create a new function group, ensure that you are using the customer namespace. You can create a new function group in the customer namespace by using transaction SE80 or SE37.
  Review Authorization: Ensure that you have the necessary authorizations to access or modify the function group. If you do not have the required permissions, contact your SAP administrator.
  Consult SAP Documentation: Refer to the SAP documentation or notes related to the specific function group you are trying to use. There may be specific guidelines or restrictions outlined by SAP.
  Contact SAP Support: If you believe that the function group should be accessible and you are still encountering issues, consider reaching out to SAP support for further assistance.
