Value Mapping in BPM

We are using Value Mapping in XI 3.0 in the integration builder under the configuration.

Value Mapping is not working during the transformation step in BPM. See help.sap.com under transformation step: http://help.sap.com/saphelp_nw04/helpdata/en/14/80243b4a66ae0ce10000000a11402f/frameset.htm

Does anybody have a solution for executing the value mapping in this case.

Thanks in advance,

Glenn van Kamperdijk
