I have been getting the following error when creating my DDT. It has not prevented me from completing my work but I would like to know what is happening? I am getting an IndexOutofRangeException Message stating that "There is no Row a Position 0.

How can I make it go away without blowing away my project work?

Well...there is really no way for me to determine that based on the stack trace and error message.  If you can, send me the PKG file and I will see if I can reproduce it.  That would be the best avenue so that I can see it in person.
