Variance Calculation:How to find incorrect orders

Hi,

I am a ABAPer. I need to know what are the process/production orders are in error while running KKS1-Variance calculation(Collecive Processing).

I am getting error message saying that "Processing incomplete. Eliminate the errors and repeat processing fo

the affected objects." To eliminate errors I need to know the orders/materials which are causing the error.

Is there any way to find the which orders/materials are causing the errors?

Thanks,

Ramesh
