Infoset Query

Hi all

i have copied an infoset with a customized name under the user group PU(purchasing) , i had added two feilds to that infoset and i have written a feild code in that particular feild, every thing is Ok with DEV 10 client , which my functional tested, and when it was moved to DEV 20 by my senoir (i dont know how to move that) he again tested and there was a dump in that.

now i want to know , how to debug the particular error where it was causing the dump. adn how to go through it.

please help me to solve this problem...i havent come across infosets earlier, this is the first time i was asked to wrok on that, where i was strucked...

thanks in advance
