Hello Venkat,
If you want to update another table then it is good that you do it at Database level not on Form level. Because if you even don't save this form, the trigger's Update statement will fire. and you will have different values on both table.
So do it at Database Table Level FOR EACH ROW Trigger on BEFORE UPDATE. Example as follows,
IF :NEW.RE_PH_NO != :OLD.RE_PH_NO THEN  --For check that if value changed then update other table.
    UPDATE AZBJ_RC_RE_DETAILS
    SET EMP_LAND_LINE=:NEW.RE_PH_NO
    WHERE EMP_OPUS_ID=:NEW.V_USER;
END IF;Regards,
