Restrict Snapshot update

Hi,

I want to restrict the snapshot quantity to be updated when a SALE or Inventory Adjustment is performed in SIM 13.2.3.

The Scenario is as below:

1. Create a 'Third Party' - 'Auto authorize' Stock count on Day 1
2. Take snapshot on Day 1
3. Start Physical count and complete the count on Day 1 using a Third Party scanner
4. Upload the Third Party flat file on Day 3.  This will upload and authorize the stock count

However, the sales transactions that takes place after the snapshot and authorization will impact the Snapshot.  We use webservices for SALES udpate.

I want to restrict the snapshot update.
