Selection dynamic Mapping Runtime Constant with a qualifier

Hello all,

i want to access a Mapping Runtime Constant out of a message mapping specified with a qualifier.

In the Integration Directory i specified in the identifier tab the following Value Pairs:

Agency Scheme Name

-

http://Sap.com/xi/XI XIParty ABC

R3D_310 Partner 111

R3T_310 Partner 222

R3P_310 Partner 333

In the message mapping i want to have the Name for the agency "R3T_310".

I know i can access the Name with:

constant = (String) map.get(StreamTransformationConstants.SENDER_PARTY);

But i getting everytime the name "ABC", which i don't want.

At this point i need your help, to find out how i can dynamically get the correct one??

many thanks for your help
