System Logs are of two different types: Those that are contained within the data base and those that are in files external to the system.

!!Internal (data base) logs
The following logs are within the data base:
;Process executions: [P2K_AM_EXECUTIONS], [P2K_AM_EXECUTION_RUN_LOGS] and [P2K_AM_PARAMETER_VALUES] track each execution of a process and the messages generated
;Session executions: [P2K_AM_SESSION_AUDITS]
;System Data Audits: [P2K_AM_CHANGE_LOGS] and [P2K_AM_CHANGE_LOG_DETAILS] is the audit detail from logging of changes (add, change and delete) for those tables/fields enabled for logging
;System Management: [P2K_AM_DATABASE_CHANGE_LOGS] identifies the patches applied to the data base
;Work Flow Management: [P2K_AM_WORK_FLOW_LOGS] identifies the execution of each work flow action and its subsequent completion.
;Approval management: [P2K_CM_APPROVAL_LOGS]

what is [P2K_AM_EXECUTION_AUDITS] used for?

!!External (file) logs

![Vertex Server|Vertex.VERTEX]
* Vertex.log - This log file is updated at the initialization of each vertex server process.  It will identify the connection to the data base and then will indicate the log file name it is switching to.  This logfile name comes from the [IMST] screen [SITE_CODE] field.  At that point this file is closed.
* ''Site_Code''.log - This log file contains information about the performance of the Vertex server, including any error messages during the execution of tax calculations.  To examine this file you must shut down the Vertex server processes.

;Maintenance: These files can be deleted periodically - it is recommended quarterly.  They are typically only examined where there is a problem with the tax calculation process

!Reports
When reports are created, the report is stored on the application sever in the directory identified by the [IMST] screen preference [ATTACHMENTS FLDR|ATTACHMENTS FLDR(System_Preference)]
