Hi Tore,

Still the thing is pretty hazy in my brain. Actually, I just got this thought as there are times when clients come to use with same 2 reports printed out of the same period but are different. Then after studying it turns out that the guy had printed one copy before and another after he has made changes to the data. This was a thought just for safety reasons.

Okay. Thanks.
