• What is the cause and solution for SAP error message SY161 - Control levels are not allowed with TABLES parameters ?

  The SAP error message SY161 indicates that control levels are not allowed when using TABLES parameters in a function module or report. This error typically arises when you are trying to use control levels (like AT FIRST, AT END, etc.) in conjunction with a TABLES parameter in a loop or processing block.
  
  Cause:
  The error occurs because control levels are not compatible with the way TABLES parameters are processed in ABAP. When you declare a parameter as TABLES, it is treated as an internal table, and control levels are not applicable to internal tables in the same way they are for standard data processing.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Remove Control Levels: If you are using control levels (like AT FIRST, AT END, etc.) in your code, you need to remove them when processing TABLES parameters. Instead, you can use standard loops to iterate through the internal table.
  Example:
  LOOP AT it_table
