Problem doing insert from one schema to another

Question

Hi all;
I have table test on schema A, and i want to create a trigger TEST_TRIG on table test, the trigger must insert data into a table X, and Y in schema B,
when i create the trigger in Aqua i got
Warnings: --->
W (1): Warning: execution completed with warning
<---
0 record(s) affected
and doing an insert on table A gives the following
ORA-04098: trigger 'A.TEST_TRIG' is invalid and failed re-validation
the trigger is
CREATE OR REPLACE TRIGGER A.TEST_TRIG
AFTER INSERT OR UPDATE OR DELETE ON A.TEST
FOR EACH ROW
DECLARE
l_auditId NUMBER(10,0);
l_auditAction VARCHAR2(1);
l_auditPK VARCHAR2(100) := :NEW.FEILD_A;
l_logInserted BOOLEAN := FALSE;
PROCEDURE auditLog
( p_column IN VARCHAR2,
p_oldval IN VARCHAR2,
p_newval IN VARCHAR2 ) IS
BEGIN
IF NOT l_logInserted THEN
INSERT INTO B.X
( auditId, auditTable, auditPK, auditAction, auditUser, auditDate )
VALUES
( B.AUDIT_LOG_SEQ.NEXTVAL,'TEST',l_auditPK,l_auditAction,'test',SYSDATE )
RETURNING auditId INTO l_auditId;
l_logInserted := TRUE;
END IF;
INSERT INTO B.Y
( auditId, auditColumn, valueOld, valueNew )
VALUES
( l_auditId, p_column, p_oldval, p_newval );
END auditLog;
BEGIN
IF INSERTING THEN
l_auditAction := 'I';
ELSIF UPDATING THEN
l_auditAction := 'U';
ELSIF DELETING THEN
l_auditAction := 'D';
l_auditPK := :OLD.FEILD_A;
END IF;
IF :NEW.FEILD_A != :OLD.FEILD_A
OR (:NEW.FEILD_A IS NULL AND :OLD.FEILD_A IS NOT NULL)
OR (:NEW.FEILD_A IS NOT NULL AND :OLD.FEILD_A IS NULL)
THEN
auditLog('FEILD_A',:OLD.FEILD_A,:NEW.FEILD_A);
END IF;
IF :NEW.FEILD_B != :OLD.FEILD_B
OR (:NEW.FEILD_B IS NULL AND :OLD.FEILD_B IS NOT NULL)
OR (:NEW.FEILD_B IS NOT NULL AND :OLD.FEILD_B IS NULL)
THEN
auditLog('FEILD_B',:OLD.FEILD_B,:NEW.FEILD_B);
END IF;
END;

Answer 1

doing select * from user_errors where name = 'TEST_TRIG' returns nothing to me.
i think there is some privilege problem cause if i create tables x and y inside schema A everything works perfectly. Any suggestion
