• What is the cause and solution for SAP error message SALV_EXCEPTION101 - Column &3 already exists (class &1 method &2) ?

  The SAP error message SALV_EXCEPTION101 indicates that there is an attempt to add a column to an ALV (ABAP List Viewer) grid that already exists. This error typically occurs when you are trying to define or add a column to an ALV table that has already been defined in the context of the current ALV object.
  Cause:
  
  Duplicate Column Definition: The most common cause of this error is that the column you are trying to add has already been defined in the ALV grid. This can happen if you are trying to add the same column multiple times in your code.
  Incorrect Logic: There may be a logical error in your code where the column addition is being executed more than once, possibly due to loops or conditional statements that are not correctly structured.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Column Definitions: Review your code to ensure that you are not trying to add the same column more than once. Look for any loops or conditions that might lead to the column being added multiple times.
  
  
  Use Conditional Logic: If you need to add columns conditionally, ensure that you have checks in place to verify whether the column already exists before attempting to add it.
  
  
  Debugging: Use debugging tools to step through your code and identify where the duplicate column addition is occurring. This can help you pinpoint the exact location in your code that is causing the issue.
  
  
  Review ALV Object Initialization: Ensure that the ALV object is being initialized correctly and that you are not inadvertently re-initializing it in a way that leads to duplicate column definitions.
