hi ,

If you insert or delete lines in the statement block of a LOOP , this will have the following effects:

• If you insert lines behind the current line, these new lines will be processed in the subsequent loop passes. An endless loop can result.
  
  
• If you delete lines behind the current line, the deleted lines will no longer be processed in the subsequent loop passes.
  
  
• If you insert lines in front of the current line, the internal loop counter is increased by one with each inserted line. This affects sy-tabix in the subsequent loop pass.
  
  
• If you delete lines in front of the current line, the internal loop counter is decreased by one with each deleted line. This affects sy-tabix in the subsequent loop pass.

Hi,

I prefer the seconde one, is simpler. Relatated to the performance I suppose it's better also, at least at network level, but only if your table is too big there is a motive for concerning. Altough is important to have good pratices,

Using sy-tabix is safer, as mentioned.
