• What is the cause and solution for SAP error message TWBH028 - Select only one list line ?

  The SAP error message TWBH028 ("Select only one list line") typically occurs in the context of SAP when a user attempts to perform an action that requires a single selection from a list, but multiple lines or entries have been selected instead. This can happen in various transactions or reports where the system expects a single item to be processed.
  Cause:
  The primary cause of this error is that the user has selected more than one line in a list or table where the system only allows for a single selection. This can happen in scenarios such as:
  
  Trying to execute a function that is designed to work with a single record (e.g., editing, deleting, or displaying details).
  Using a report or transaction that requires a specific entry to be selected for further processing.
  
  Solution:
  To resolve the TWBH028 error, follow these steps:
  
  
  Review Your Selection: Go back to the list or table where the error occurred and ensure that you have selected only one line. Deselect any additional lines that may have been inadvertently selected.
  
  
  Use the Correct Functionality: If you need to perform an action on multiple entries, check if there is a different function or transaction that allows batch processing. Some transactions may have options for mass changes or processing multiple records.
  
  
  Check for Filters: If you are using filters or search criteria, ensure that they are set correctly to narrow down the results to a single entry.
  
  
  Re-attempt the Action: After ensuring that only one line is selected, try to execute the action again.
  
  
  Related Information:
  
  Transaction Codes: The error can occur in various transaction codes depending on the context (e.g., ME23N for purchase orders, VA03 for sales orders, etc.).
  User Training: If this error occurs frequently, consider providing training or documentation to users on how to properly select items in lists.
  SAP Notes: Check SAP Notes or the SAP Support Portal for any specific notes related to the transaction you are using, as there may be known issues or additional guidance.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP documentation for further assistance.
