In Store Inventory Management (SIM): 

Some transactions can happen during a Unit & Amount (U&A) stock count while other transactions should be prevented from HAPPENING during a count. Sales and inventory adjustments can update the snapshot; sales because SIM cannot control that information unlike all the receiving and SHIPPING transactions, and inventory adjustments because these sometimes are REQUIRED in case something breaks during the count. 

In RETAIL Price Management (RPM): 

The behavior should be consistent across the transaction types. Customers using SIM will want to avoid updating the snapshot, as SIM does not do this.
