Regarding receiver determination problem in IDOC-XI-XML file scenario

Dear All ,

In IDOC-XI-xml file scenario , I have configured SLD , IR . But in ID , after file adapter , reciever agreement configuration when I am doing receiver determination configuration I am not able to insert mapping program in configuration overview of receiver determination as I am not getting "New Specific" option in mapping .

Can anybody suggest what could be the reason behind this .

Thanks in Advance
