STRs passed from APO to ECC as 'firmed'

I am using APO V5.1 connected to ECC 5.

I am creating stock transfers in APO and passing these to ECC via standard CIF processing.

I note that the stock transfers appear as 'firmed' in ECC.

Is there a way of passing the STRs to ECC as not firmed.

Thanks for any advice on this...
