So if I understand you correctly:
SELECT oid, concepte, deure, haver,
delta_sum + ( SELECT SUM( COALESCE( A3.deure ) - COALESCE ( A3.haver ) )
FROM Assentaments A3
WHERE A3.compte = '572000001'
AND A1.data BETWEEN '2007-01-15' AND '2007-01-30' ) AS starting_Sum
FROM( SELECT A1.oid, A1.concepte, A1.deure, A1.haver,
sum( COALESCE( A2.deure, 0 ) -
COALESCE( A2.haver, 0 )) AS value_sum
FROM Assentaments AS A1
INNER JOIN Assentaments AS A2
ON A1.oid >= A2.oid
AND A1.numero = A2.numero
WHERE A1.numero=11189
GROUP BY A1.oid, A1.concepte, A1.deure, A1.haver
ORDER BY A1.oid ) AS Summed_Assentaments( oid, concepte, deure, haver, delta_sum );
