Mapping issue DEBMAS06

Hi all,

I have a DEBMAS06 structure like this:

DEBMAS06

E1KNA1M

KUNNR

LAND1

NAME1

ORT01

PSTLZ

REGIO

STRAS

BRAN1

E1KNVVM

E1KNVPM

PARVW

KUNN2

and PARVW can have AG, RE, WE

KUNNR PARVW KUNN2

0000300027 AG 0000300027

0000300027 RE 0000300016

0000300027 WE 0000300016

I'm having problem mapping, I have a situation where,

if WE partner = KUNNR , assign PRIMARY else rest all Independent.

So here I need to query PARVW and see weather it has WE and later compare its KUNN2 with KUNNR.

Can someone help me with the mapping.

Thanks,

Srinivas
