Inserting some rows with SqLite (Java Android)

im trying to insert multiple rows in my database (Sqlite), but, for example, when i get an object with 5 rows, and trying to insert into my db, it just insert 3 rows, so 2 of them skips.

I did some logs, and i'm getting this 5 rows, but just inserting 3.

(Sorry my bad english)

for (DocumentLiniaAutoventa dla : document.linies){

                ContentValues valueslinies = new ContentValues();
                valueslinies.put("empresa", dla.empresa);
                valueslinies.put("tipusdocument", document.tipusdocument);
                valueslinies.put("any", dla.any);
                valueslinies.put("serie", dla.serie);
