Dependent SCA for EJB DC on Track

Hi,

I have created a EJB DC in the Track, When I try to build the DC getting the following error. Please let me know, what dependent SCA need to add to track. I am working on CE7.2 sp4

ERROR: Check for used DCs failed: Used component not found: sap.com/tc/esi/esp/wsrm/façade

Thanks in advance,
