Problem with Control Break Statements
Sometime At first statement is not trigger due to some technical issue like we trying to call at first MATNR from IT_MSEG internal table where MBLNR listed first and MATNR is listing in third column so here At first MATNR will not trigger, to solve this issue we must adjust our internal table and get MATNR on first column.
