Supply/Demand Inclusion Rule for Cancelled lines

Hi All,

We are running R3465 every night to extract sales demand after End of Day processing jobs are completed. Currently the inclusion rule is based on next status, so the cancelled lines are at Last Status  980/999 (during Order Entry) or 983 (Cancelled during pick confirmation) or 984 (Cancelled during Ship Confirmation). These lines are getting picked up because the next status is at 999, so how to exclude the cancelled line.

Thank you
