AX2012 Retail: Microsoft Dynamics AX for Retail Offline Sync Service fails to synchronize transactions from offline database

Synchronization
issue between Offline database and Store database

Issue description

 We recently had a case where an offline POS refused to sync transactions to the store database after
it came back online.  This retail systemconsisted of a centralized store database and an offline database for each of
the POS machines.   On each POS the Microsoft Dynamics AX for Retail Offline Sync Service was running to synchronize the offline database with the
store database. The offline databases were created using the Retail Database Utility and had data, so offline sync had been working at one point.

Troubleshooting

To troubleshoot, we enabled tracing on the AX for Retail
Offline Sync Service as described in this article:  

The outcome was following:

Solution

We discovered that the store database was missing three tables that manage the sync configuration:  scope_info, scope_config, and schema_info. 

These tables are normally created in the process of creating any new offline database using the Retail
Database Utility.  In order to recreate these tables in just the store database we created a new offline database using
the utility (making sure to create a backup of the existing offline database).  After this we ran the N-1095
job and restarted the AX for Retail Offline Sync Service which resolved the issue.
