We have a report which we customize, since beginning of Baan, we are using that report yesterday I added some lines under script using IF condition, first time it gives me the correct output for IF condition using the report the next time it is not giving the correct out put for the mention IF statement. When I am compiling there are No errors & NO warnings.

My doubt report is not modifying the contents in dynamic link library, my question how to update the contents under DLL.

Any one having the same issue, reply to me what to do.

Your question needs some more information to be analyzed, the clues you give are so vague that it's impossible for anyone to give you an answer.
You have modiified the script or the report script?
The DLL is linked to the script or the report script?
If your doubt is about the DLL, why don't you debug the DLL and the session itself to investigate?

I had modified the script for the report.
DLL'S are link to report, I dont have any help how to use debug the session.

You mean haven't the script for DLL or you never debug a script before?

Yes your correct this is not for DLL script, this is for report script. Earlier I had not run the script under debugger mode, if you have any help on this reply to me the link.
