Transactional Iview + Excel problems

Hi, i have a problem that i can't find the solution.

I have a Z program in R3 where you can select an Excel file from your pc, then when you execute it, there's a batch input and read the excel. It's works fine, but the problem is that i have a transactional iview of this program and when i try to execute it always displays an error. The problem is because some internal tables are empty.

I do not know where is the problem, please i need your help.

Regards,

Sebastiá
