reg problem in Runtime Constants $SenderService

Hi

Have a problem , I am using ABAP XSLT Processor mapping (I have used message split for this particular scenario i.e. input is single file and output is multiple file)

Instead of hard coding the sender service i tried to use Runtime Constants $SenderService but this was not working .

For one to one scenrio it is working fine ,also in JAVA XSLT Processor it is working fine ....

can any one help on this
