CIF queues of FC* type

Hi All,

We recently had APO service pack upgrade from SCM 7.02 SP8 to SCM 7.02 SP15.

Post upgrade, we are seeing CIF queues of FC* type is getting generated and are in READY state in SMQ2 in APO.

We do not have FC* registered in SMQR in APO.

We did not get these CIF queues before upgrade.

I went through the below link.

Is anybody familiar with FC* CIF queues and what is the impact if we register them in SMQR in APO?

Look forward to your quick response.

Thanks in advance,
