    Hello Shankar,

    I guess you want to delete the line from the list directly, am I correct?

    If yes, then you can have a button on the toolbar in the list. When the user selects a line and clicks that button, the line will get deleted.

    Now, what has to be known is, do you want the line to be deleted only from the list, or from the internal table in the program also?

    Regards,

      Hello Shankar,

      I have also given you a code for that. The first one that have given you will leave those blank lines on the output and it doesn't look all that <i>neat</i>, as you would call it.

      But please refer to my next post, hwere the blank lines will no longer be visible.

      Regards,

    Great solution Anand !

    -skip <b>to</b>- (never heard), we all can learn from you !

    My solution for such a problem is different:

    I'll try to filter data, which is not required before output / appending table.

    e.g.

    Loop at itab1.

    If itab1-qty = 0.

    Delete itab1.

    else.

    Append sth to itab2.

    Endif.

    Endloop.

    regards Andreas

      Hi Andreas,

      Firstly, I must thank you that you have liked the SKIP TO method.

      Secondly, your solution , I'm afraid is not exactly appropriate in this case. I shall try to explain it to you.

      Let us say you have two internal tables, one with (Material, Material Type) and the other with (Material, Material Description). You want to have a list with three fields : Material , Material Type , Material Description.

      Now obviously, this is some kind of a join operation that we want on the <i>internal tables</i>. Here, you would have to fill another internal table by looping at these two internal tables. Then you will loop at the final internal table and display the entries.

      The point here is performance: You have to loop at the two internal tables anyways. Why do we need to fill another internal table in the process and then use that to display the data? Especially when the entries get large, this might be significant.

      Moreover, when the user does not have to change anything on the list, we do not even have to worry about deleting the entries in the internal table, since they are not going to be used further in the program.

      But there is the other side to it as well. Your solution, I must admit, is more intuitive than mine. The logic is fairly simple to understand. If a programmer is not comfortable with the SKIP statement, then he's going to have a very difficult time debugging in case there are any errors :-).

      Regards,

      Anand Mandalika.
