Loop Identifier Code

String (AN)

Mandatory

Code identifying a loop within the transaction set which is bounded by the related LS and LE segments (corresponding LS and LE segments must have the same value for loop identifier). (Note: The loop ID number given on the transaction set diagram is recommended as the value for this data element in segments LS and LE.)

Figures Appendix

Following is a figure detailing the use of the LE and LS segments in conjunction.

LE is a control segment. LE is always used in conjunction with a corresponding loop header (start) - LS, as illustrated below. The LS and LE indicate the start and end of a loop but are not part of the iteration of the loop.

LOOP NESTING

Loop "A" Header (LS "A")
            Loop "B" Header (LS "B")
                        Loop "C" Header (LS "C")
                        Loop "C" Trailer (LE "C")
                        Loop "D" Header (LS "D")
                        Loop "D" Trailer (LE "D")
            Loop "B" Trailer (LE "B")
Loop "A" Trailer (LE "A")

Neither LS nor LE is used if the data within the loop is not used.
