Update termination while creating billing

Hi All,

I have created adobe form and attached to one output type and when i am trying to create invoice from sales order system is giving updat termination message.

Could you please anyone tell me where is the exact problem in adobe form or in driver program.(Adobe form has been devloped in Finnish language )

I checked SM13 and there i can see RV_MESSAGE_UPDATE function module with error description.From that I am not able to trace.

Regards,

Sachin
