• What is the cause and solution for SAP error message WER247 - All fields of table &1 have already been selected ?

  SAP Error Message:
  
  WER247 – All fields of table &1 have already been selected
  
  Cause:
  This error occurs when you try to select all fields of a database table in an ABAP program or query, but the system detects that all fields of the specified table have already been selected previously. Essentially, the system prevents redundant selection of all fields from the same table multiple times.
  For example, if you have a SELECT statement or a query that tries to select all fields (SELECT *) from a table that has already been fully selected earlier in the same context, SAP raises this message.
  
  Explanation:
  
  The message parameter &1 contains the name of the table.
  The system tracks which fields have been selected from tables in the current context.
  Selecting all fields again from the same table is unnecessary and can cause ambiguity or redundancy.
  This is often encountered in dynamic SELECT statements, queries, or when using function modules or tools that build SELECT statements dynamically.
  
  
  Solution:
  
  Avoid selecting all fields multiple times: Review your code or query logic to ensure that you do not select all fields from the same table more than once.
  Select only required fields: Instead of using SELECT *, specify only the fields you need.
  Check dynamic SELECT statements: If your program builds SELECT statements dynamically, add logic to check if the table fields have already been selected.
  Debug and trace: Use debugging or SQL trace tools (ST05) to identify where the redundant selection occurs.
  In queries: If this happens in SAP Query or Infoset Query, check the Infoset or Query definition to ensure the table is not included multiple times unnecessarily.

  Summary:
  
  Cause: Attempt to select all fields of a table that have already been selected.
  Solution: Avoid redundant selection; select only needed fields; check query or program logic.
  Check: Query definitions, dynamic SELECT statements, and debug if necessary.
