It looks like the RETURN NEW is inside the exception handler recovery
block, which is not where you want it.  When I run this example I get

ERROR:  control reached end of trigger procedure without RETURN
CONTEXT:  PL/pgSQL function "ECISDRDM"."TRIGGER_FCT_TR_STG_APPLICATION_CDIM_INS"()

So there is something seriously wrong with however you are testing
this, if you failed to notice that.
