Delete a row in in a loop using model builder

[IsmaeelAbdulrahman]

Hi, I have a model builder with a point-layer input. My objective is to take every row from the input once a time and apply some functions and then go back to the second row (i.e. I have a loop) updating the old layer (delete the first row). What tool should I place after the input layer to take a single row (an element) once a time and then go back to the second and do the rest. The input name in the picture is 'sort'.

Any idea or example will be appreciated it. Thanks.

This is the only tool that comes to mind... if you really need to delete it

Delete Features—Help | ArcGIS for Desktop which I don't see the purpose, perhaps you want an iterator

Thanks Dan, I am new and not good in programming and still I am trying to finding someway to do it by using only the blocks (functions) available in the builder.

yes, that is why I recommended them since tools can be used in modelbuilder and iterators can only be used in models
