• What is the cause and solution for SAP error message W+658 - More than one selection field was entered ?

  SAP Error Message:
  
  W+658 More than one selection field was entered
  
  Cause:
  This warning message occurs when a user enters values in more than one selection field in a selection screen or report where only one selection field is allowed or expected. The program logic or selection criteria is designed to accept input in only one of the possible selection fields at a time, but multiple fields have been filled, causing ambiguity in the selection.
  For example, a report might have two mutually exclusive selection parameters (e.g., "Customer Number" or "Customer Group"), and the user has entered values in both fields simultaneously.
  
  Solution:
  
  Check the selection screen input: Review the selection fields and ensure that only one of the mutually exclusive fields is filled.
  Clear other selection fields: Remove entries from all but one selection field.
  Follow the program instructions: If the program documentation or selection screen indicates that only one field should be entered, adhere to that rule.
  If multiple fields are required: Check if the program or report has an option or variant that allows multiple fields to be entered. If not, you may need to run the report multiple times with different selection criteria.
  Consult the program documentation or developer: If the behavior is unclear, check the documentation or contact the ABAP developer to understand the intended use of the selection fields.
  
  
  Related Information:
  
  This message is a warning (W), not an error, so the system allows you to continue but advises you to correct the input.
  The message number W+658 is specific to the program or module you are using; the exact message text might vary slightly depending on the context.
  This kind of message is common in reports or transactions where selection screens have multiple input fields that are logically exclusive.
  If you are a developer, you can check the selection screen logic in the ABAP code, typically using SELECT-OPTIONS or PARAMETERS statements, and the validation logic in the AT SELECTION-SCREEN event to enforce this rule.
  
  
  Example:
  If a report has two parameters:
  
  PARAMETERS: p_cust TYPE kunnr.  
  PARAMETERS: p_custgrp TYPE kna1-kdgrp.
  
  And the user enters values in both p_cust and p_custgrp, the system will issue message W+658 to indicate that only one should be entered.
  
  If you provide the exact transaction or program name, I can help you with more specific guidance.
