Hi Lowell

I've thinking about it but in that case it should happen every time we process the same input...

We reprocess the input and it commits ok, without ANY source code or SP change...

the first time i post this the input comes from a web page and I wasn't able to find an exception

this time comes from a kind of batch input so we were able to reprocess and also we get an exception but the symptoms are the same: only data from a SP from 6 was persisted, the one that internally uses BEGIN TRAN... COMMIT TRAN

thanks for your comment!
