Hi,

We have a home made developed report script that sometimes shows the data from the main data table but sometimes it doesn´t / puts zeroes instaed. The main data table comes from a customized session. Any idea?

Without the script, or at least the select statement from it, I don't think anyone will be able to help you. Unfortunately, your question is too broad and leaves too many variables open. However, if someone does have an idea, please do share.
