Message Mapping Sort IDOC Segment Values

HI,

I have an IDOC with multiple E1EDK12 segments.

Each segment has a field MATNR. I have to create only one target node with E1EDK12 which has highest value for MATNR.

Please help how could i achieve this in PI

(source)E1EDK12 (1 to many) ----> Details (Target) occurrence:  1  (E1EDK12 with highest MATNR)

Lets say i have 4 E1EDK12 segments. each segment has one MATNR

1. E1EDK12->MATNR = 2376

2. E1EDK12->MATNR = 2271

3. E1EDK12->MATNR = 3376  (highest)

4. E1EDK12->MATNR = 1176

I have to create only one target node with all values in E1EDK12 which has MATNR = 3376

Thanks
