It comes handy, when you need to allocate the next item number of a document. The task is always to get the highest number first.
DATA: po_items TYPE STANDARD TABLE of ekpo. DATA(max_num) = REDUCE numc5( INIT res = '00000' FOR line IN po_items NEXT res = COND #( WHEN line-ebelp > res THEN line-ebelp ELSE res ) ).
You can also get the lowest number, the complexity of comparison is up top You to do something different with a particular column. Here the focus is on the new REDUCE statement.
Applicable in NW 7.5 and onwards.
