The Support Debugging Tool (SDT) is an invaluable resource for administrators and developers. It allows for advanced logging, tracking of SQL commands, and modification of GP behavior.

• Logging: Enable detailed logging of GP processes, including SQL statements executed, Dexterity script execution, and Win32 API calls. This can help identify precisely where an error occurs.
• Security Profiler: Analyze security privileges to determine why a user cannot access a specific window or perform an action.
• Resource Monitoring: Monitor memory and CPU usage within the GP client.

SQL Server Management Studio (SSMS)¶

SSMS is the primary tool for interacting with the Dynamics GP databases.

• Querying Data: Execute SQL queries to inspect data integrity, verify setups, or retrieve information about errors.
• Database Maintenance: Perform index rebuilds, update statistics, and manage transaction logs.
• Security Management: Manage SQL Server logins and database users.
• Activity Monitor: Identify blocking queries, long-running transactions, and resource contention.

Performance Monitor (PerfMon)¶

Windows Performance Monitor can be used to track system resources (CPU, Memory, Disk I/O, Network) on both the SQL Server and client machines, helping to pinpoint hardware or resource bottlenecks.

Event Viewer¶

Windows Event Viewer provides logs for system, application, and security events. Always check these logs on both the GP client and server when an issue arises, as they often contain critical error details that are not visible within GP itself.
