Receive Consignment Pick-up into Blocked

Hi Guru

I’m seeking how to change the stock type of consignment pick-up from current “Unrestricted”
to “Blocked” without changing Availability checking rule. 

Current conditions are as below.

Sales document type: KA (Consignment Pick-up)

Returned item category: KAN

Once I changed the movement type of the schedule line used in this item category from
632 to 657, but this movement type 657 impacted changing Availability check rule, too.

So please teach me what should I do for changing stock type as “Blocked” on
consignment pick-up but not change the Availability check rule.

Thanks

Yuich
