Sql retroactive query

Question

Hail sql-gurus!!! :) I'm here to explain a little problem i'm having with an sql statement. I hope somebody can help me!! at the end i'll put my query to see if somebody can fix it (sorry about my poor english).
Ok, to understand what I want to do with my query I'll explain the meaning of some columns (only one table involved).
-AV_ID unique identifier
-AV_ID_PARENT define the hierarchy when exists.Example: one row has AV_ID 50 with no AV_ID_PARENT, this is a level one object. Second example: one row has AV_ID 300 and AV_ID_PARENT 50, this is a level two object. Simple!!
-AV_NSERIE this is a object serial number
-AV_FECHA_INI this is a start date of the object (not relevant to explain it more)
-AV_CONTRATA_ID One kind of object
-AV_PARTNER_ID Property of the object
-AV_FECHA_CIERRE_ADM Finish date of the object
-AV_ESTADO Status of the object
Let's go!! we have a unique table (XXWAVISOS). We have different objects hierarchiced between them. Now I want a query in which results has only first level objects (I suppose this are the rows without AV_ID_PARENT) that has AV_CONTRATA_ID=8, AV_PARTNER_ID=1, AV_FECHA_CIERRE_ADM between '01/07/2007' and '28/08/2007', AV_ESTADO='CERRADO'.
Ok this query is simple even for me, but now here comes the complication: I want in the results a new column (with boolean value) that differences between objects (always we are talking about first level objects) that has another object in the table with the same serial number (AV_NSERIE) and with a start date (AV_FECHA_INI) no lower than 30 days in the same field (AV_FECHA_INI) and no greater. If this rule matchs, it must mark in the new column.
This is my not working properly query:
SELECT
POSTERIOR.AV_ID "Num. Rexion",
POSTERIOR.AV_NUM_ALT "Num. Contrata",
POSTERIOR.AV_PARTNER "Partner",
POSTERIOR.AV_RECURSO "Asignado a",
TO_CHAR(POSTERIOR.AV_FECHA_FIN,'DD/MM/YYYY HH24:MI') "Fecha Fin",
POSTERIOR.AV_MOD_DESC "Modelo",
POSTERIOR.AV_NSERIE "Num. Serie",
POSTERIOR.AV_CLIENTE "Cliente",
CASE WHEN
POSTERIOR.AV_ID IN (
SELECT
ANTERIOR.AV_ID
FROM
XXWAVISOS ANTERIOR
WHERE
ANTERIOR.AV_NSERIE=POSTERIOR.AV_NSERIE
AND
ANTERIOR.AV_ID_PARENT IS NULL
AND
ANTERIOR.AV_FECHA_INI>POSTERIOR.AV_FECHA_INI-30
AND
ANTERIOR.AV_ESTADO='CERRADO'
AND
ANTERIOR.AV_CONTRATA_ID=POSTERIOR.AV_CONTRATA_ID
AND
ANTERIOR.AV_PARTNER_ID=POSTERIOR.AV_PARTNER_ID
AND
ANTERIOR.AV_FECHA_INI<POSTERIOR.AV_FECHA_INI
THEN 'SI'
ELSE ''
END "Es Re-repair"
FROM
XXWAVISOS POSTERIOR
WHERE
AV_CONTRATA_ID=8
AND
AV_ESTADO='CERRADO'
AND
AV_PARTNER_ID=1
AND
AV_ID_PARENT IS NULL
AND
TRUNC(AV_FECHA_CIERRE_ADM)>=TO_DATE('01/07/2007','DD/MM/YYYY')
AND
TRUNC(AV_FECHA_CIERRE_ADM)<=TO_DATE('28/08/2007','DD/MM/YYYY')
What I want is (four example possible cases):
If an object (first level object) has a serial number:12345 with a start date:12/08/2007 and we have another object (first level object) with the same serial number and a start date:27/07/2007. In this case, we want to remark the new column with a 'SI'.
If an object (first level object) has a serial number:12345 with a start date:12/08/2007 and we have another object (first level object) with the same serial number and a start date:27/02/2007. In this case, we don't want to remark the new column, it must be blank.
If an object (first level object) has a serial number:12345 with a start date:12/08/2007 and we have another object (second level object) with the same serial number and a start date:27/07/2007. In this case, we don't want to remark the new column, it must be blank.
If an object (first level object) has a serial number:12345 with a start date:12/08/2007 and we have another object (first level object) with the same serial number and a start date:27/09/2007. In this case, we don't want to remark the new column, it must be blank.
So this is the best puzzle I've built!!!! Now, I must solve it. I hope the explain was clear, give me a clue please!!!!
Thank you in advance.

Hi N. Gasparotto, thanks for replying, this is a script to create the sample table:
create table XXWAVISOS
AV_ID NUMBER not null,
AV_ESTADO VARCHAR2(20),
AV_FECHA_INI DATE,
AV_ID_PARENT NUMBER,
AV_NSERIE VARCHAR2(40),
AV_PARTNER_ID NUMBER not null,
AV_CONTRATA_ID NUMBER,
AV_FECHA_CIERRE_ADM DATE,
AV_NUM_ALT VARCHAR2(40),
AV_PARTNER VARCHAR2(40),
AV_RECURSO VARCHAR2(40),
AV_FECHA_FIN DATE,
AV_MOD_DESC VARCHAR2(40),
AV_CLIENTE VARCHAR2(50)
And this is a script to insert 11 data rows:

The expected result is:
4 rows (AV_ID 1,3,5 and 7), but in the new column "Es Re-repair" only AV_ID 1 and 7 has 'SI'
You can see the expected results in this file: http://www.rexion.es/descargas/result.xls
Please help!!! Thanks in advance.
