Currently i working on Navigantional Attribute Scenario.I have created one basic characteristics i.e
ZLOCNO & in Attribute Tab i have added ZDESCENT Attribute Characteristics(Which is already Created).
In MPOS i have taken two char. i.e 9AMATNR & ZLOCNO.
I have created Master Data( Value) for NA Char. i.e. T (Thane) , A (Andheri),D ( DADAR) & For ZLOCON
i have created Value is MUMBAI with above Distribution Center.But problem is that whenever I created First value i.e Location Mumbai & Distribution Center T (Thane),System is accepting.But when i am going to create other combination i.e Location MUMBAI & Distribution Center D (DADAR) or A (Andheri),System is not accepting & showing error "A data record with the same key already exists".
But client would like to see Different Distribution Center under one location.
Can anyone tell me where i am doing mistake?
Thanks in Advance
