Not all control paths lead to a return statement. (SBL-SCR-00128)This issue was fixed in version 126.96.36.199, but has been reported re-occurring in IP2014 patchset 3, it is caused due to product defect. This can cause interruptions in full compile of srf.
While compiling srf, if any script which has try catch block which has return statement in try block and does not have return statement outside catch, then this error will interrupt the srf compilation.
To resolve this disable the "Deduce Types" scripting option in Siebel Tools as shown below.
