Inbound Queues in SRM 7.0

Hello Experts,

We have SRM 7.0 / Classic scenario with ECC as a backend system.

We observe in SMQ2, we have couple of queues. But I do not know if these have any releveance to us.

We maintain filters(R3AC1 and R3AC3) for Material master and Product Categories master for pulling in data from ECC

Clik here to view.

Is is advisableto de-activate these queues?  What information is pulled with these Queues?

Thanks,

Dhananjay
