E1EDK21 segment will come N number of times in message.
E1EDK21 segment has 3 segments ORMNG,LFIMG and POSNR.
The condition is -
If [sum of all ORMNG segment] is equal to the [sum of all LFIMG with POSNR starting with '4' ] then CREATE Target Field EFIELD.
Can we achieve it using graphical message mapping. As I see sum of segments , i thought it can be achieved by UDF only. If so, please help in UDF for it.
