POS Synchronize Concept

2. What is POS Synchronize Local Area Network (LAN)2
To send and receive data between HQ and Outlet databases.
Users can connect each others through VPN connection (Hamachi or other VPN software) or local network. HQ HQ

4. Sync Profile Always set at HQ account book.4
Always set at HQ account book.
Proper to manage and distribute all the terminals in each profile. (It depend on internet speed, database size)
Always set to one way sync (HQ to outlets)

5. Sync Profile 5
When perform change code at outlet, it will prompt out sync profile let user to choose, and then it will use the HQ DBSetting to remote change code at HQ database.
If the last all outlets synced date is more than 5 days from today date. It will not allow you to change code unless you perform speed sync first.

6. Sync Profile Status 6 GREEN: Synced until today date
Profile Name
The date time of last master data finish sync
The date time of last start sync
The date time of last finish sync
The date time of last transaction data finish sync
The date time of last all outlets finish sync
Status
GREEN: Synced until today date
ORANGE: 1 day and above no sync
RED: days and above no sync

Checking HQ connection…
Checking DB version…

9. Full Sync You must perform full sync once setup a new sync profile.9
You must perform full sync once setup a new sync profile.
Full Sync will copy all master data from HQ to all outlets without trigger any change code.
Full Sync is always perform two way sync to make sure all data is tally.
Do not perform any Insert, Delete, and Change Code for master data during Full Sync.

14. Speed Sync 14
Perform speed sync after run successfully full sync once setup a new sync profile.
Speed Sync will run faster and trigger for change code. (Based on table called ChangeLog)
Speed Sync is same with auto sync when you have set auto sync services.

39. Error 10: “The Alternative Item Code xxx is duplicated for Item Code xxx”39

40. Things To Check 40 Solution:
Make sure the alternative code is not duplicated between different item code.
If allow to duplicated, tick the option “Allow Duplicate Itemcode, Barcode and Alternative Code”
