Looping |

The label LOOP ID - N1 refers to a loop, or a set of segments that can be repeated. The slide shows the N1 segment, which is the most commonly looped, or repeated, set of segments in a purchase order.
The label Loop ID - N1 means that if you want to use this particular
set of looping segments, you must always start it with the N1 segment.
On the right side of the banner there's a number - in this case, the number
is 200. This says you can have up to 200 occurrences of this loop.
