• What is the cause and solution for SAP error message WS_TOOL152 - At least one function of function group &1 must be selected ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WS_TOOL152: At least one function of function group &1 must be selected
  
  Cause:
  This error occurs when you are working with function groups in the SAP development environment (typically in the Function Builder or when generating function modules) and you attempt to perform an action that requires at least one function module to be selected within a function group, but none has been selected.
  In other words, the system expects you to select or specify at least one function module from the function group &1 (where &1 is replaced by the actual function group name), but you have not done so.
  
  When does it occur?
  
  When generating or activating function groups or function modules.
  When trying to transport or modify function groups without selecting any function modules.
  When using tools or transactions that require you to select function modules within a function group, but you leave the selection empty.
  
  
  Solution:
  
  Select at least one function module within the function group before proceeding.
  If you are in a selection screen or dialog, make sure to mark or highlight at least one function module.
  If you are creating a new function group, ensure that you create and assign at least one function module to it.
  Review the function group contents in transaction SE37 (Function Builder) or SE80 (Object Navigator) and verify that function modules exist and are selected as required.
  If you are using a custom tool or report, check the selection criteria and ensure that the function modules are properly selected.
  
  
  Additional Information:
  
  Function Groups are containers for function modules in SAP. They group related function modules together and share global data.
  This error is a validation message to prevent operations on empty or incomplete function groups.
  The message text can be found in the message class WS_TOOL.
  If you are unsure which function modules to select, consult the development documentation or the ABAP team responsible for the function group.
  Sometimes, this error can appear during transport or upgrade activities if the function group is empty or incomplete.
