How to get the Receiving BU quantity updated when trying to replenish from another INV BU (sender)

We are trying to replenish an INV BU (receiver) from another INV BU (sender) - while doing so, we were able to create a requisition from the replenishment process and we got a MSR created when we sourced the requisition.

After completion of the fulfillment for the MSR, we were expecting the available quantity on the receiver BU to increase but this did not happen. However, the quantity on the sender BU got reduced.

Is/Are there any other steps that need to done for the receiver BU to show the increased quantity?

Any help is appreciated.

Thanks
