Shopping Cart: "Error In Process" status ?

Hi everybody,

Finally I can create and submit a shopping cart (describe requirement). Now, jusf after the approval (1-step approval) the SC'status is "Error in Process".

I would like to know how to debug this error in order to see the real cause ? or, somebody knows how to solve this specific error?

pd: Now I opened this thread, so I'll be able to give reward points.

I really appreciate your help, thanks !
