Obviously SUM1 is flown from another field. (Calculation filed)
SUM1, GTOT will be Global Variables. and S_TPREV will be from interface. (s_tprev can be in the form wa_ekpo-ebeln )
I hope you've understood that, SUM1 will be GTOT will be equal to S_TPREV in the first run of loop and as the loop runs the GTOT will be incremented by the S_TPREV value of respective line item, until the internal table ends.
Hope you get some clues from this.
