How to file a T5018 with missing BN/SIN?

I am missing a SIN/BN for one of the trades my client used. Is there a way to override that field so I can still transmit the T5018 slips? We are unable to find the trades person.

I have done both the first and second review for the field but I am still being told to resolve outstanding errors before transmitting.

I have filed T5018 slips with missing information before but not with Taxcycle.

Thanks Michelle.

I just tried all 0’s for the BN and it looks like I can transmit now.
