Configure Business Central Server
APPLIES TO: Business Central 2022 release wave 2 (version 21) and later. For later versions, see Configuring Business Central Server in outdated versions.
Note
Azure Active Directory is now Microsoft Entra ID. Learn more
When you run Business Central Setup and install Business Central Server, you provide information that is then used as the configuration for the default Business Central Server instance. This information is stored in a configuration file for the server instance called CustomSetting.config. The default location of the CustomSettings.config file is C:\Program Files\Microsoft Dynamics 365 Business Central\NNN\Service.
After you install Business Central Server, you can change any of the settings, including other settings that weren't available to you in Setup.
Note
Each Business Central Server instance has its own CustomSettings.config file.
Configure Business Central Server in Setup
You configure the default instance of Business Central Server by running Business Central Setup and selecting one of the following options:
- Demo Option
- Server Option
- Developer Option
- Customize > Server
After you specify an installation option or customize your component list, the Specify parameters pane is displayed in Setup. The list of parameters that you see depends on which components you've selected for configuration. Setup provides a short description for each parameter.
Configure Business Central Server after installation
After you install Business Central Server, you can change the configuration settings in the CustomSettings.config file of a Business Central Server instance in the following ways:
Using the Set-NAVServerConfiguration cmdlet that is available in the Business Central Administration Shell.
Learn more in Using administration shell cmdlets to modify settings.
By directly editing CustomSettings.config using a text editor.
We recommend that you don't directly edit the configuration file, because if you make any errors in typing, the server instance might not start.
Restart Business Central Server after modifications
If you use the Business Central Server Administration tool or modify the CustomSettings.config file directly, you must restart the Business Central Server instance before any changes can take effect.
The Set-NAVServerConfiguration cmdlet doesn't always require restarting the server instance. It depends on the configuration setting that you change. There are several settings that are dynamically updatable. Dynamically updatable means that a server instance restart isn't necessarily required after modification. Learn more in Modifying dynamically updatable settings.
These settings are indicated by the text Dynamically updatable: Yes in the tables that follow,
Business Central Server instance settings
This section describes all the configuration settings for a Business Central Server instance. The settings are grouped according to the tabs under which they appear in the Business Central Server Administration tool. The Key Name column displays the name of the setting as it appears in the CustomSettings.config file. It's also the name for the setting when you run the Set-NAVServerConfiguration cmdlet.
General settings
The following table describes general settings for the server.
| Key Name | Description |
|---|---|
| ALLongRunningFunctionTracingThresholdForApplicationInsights | Specifies the amount of time (in milliseconds) that an AL function can run before a warning event is recorded in the partner's Application Insights resource trace log. If you don't want a threshold, set the value to -1. To collect this telemetry data, the Application Insights Instrumentation Key setting must be configured. For information about analyzing this telemetry, see Analyzing Long Running AL Methods Telemetry. Default: -1 Dynamically updatable: Yes |
| ApplicationInsightsConnectionString | Specifies the connection string of the Application Insights resource in Microsoft Azure to use for gathering and analyzing telemetry data emitted by the server instance. When this setting is configured, the server instance will send telemetry data to Application Insights for analysis and presentation. This is the recommended setting instead of the Application Insights Instrumentation Key. If both settings are used, the Application Insights Connection String takes precedence. This setting only applies to a server instance that is configured as a single-tenant instance. For a multitenant server instance, this setting is ignored, and the Application Insights resource is set on a per-tenant basis, when tenants are mounted. Learn more in Enable Sending Telemetry to Application Insights. Default: empty Dynamically updatable: No |
| ApplicationInsightsInstrumentationKey | Specifies the instrumentation key of the Microsoft Azure Application Insights resource to use for gathering and analyzing telemetry data emitted by the server instance. This setting can be used as an alternative to the Application Insights Connection String setting. It's ignored if the Application Insights Connection String is also specified. This setting only applies to a server instance that is configured as a single-tenant instance. For a multitenant server instance, this setting is ignored, and the Application Insights resource is set on a per-tenant basis, when tenants are mounted. Learn more in Enable Sending Telemetry to Application Insights. Default: empty Dynamically updatable: No |
| ClientBuildRestriction | Specifies what happens when a Business Central client tries to connect to the Business Central Server instance when the client is running a different build version of Business Central than the server instance.

The user can choose to continue or cancel the connection. DoNotAllow A message appears that informs the user that the client and server instance build versions are different. The client doesn't connect to the server instance. Note: With the Business Central Web client and Business Central tablet client, this setting compares the build version of the Business Central Web Server on IIS with the Business Central Server instance. It controls the connection between Business Central Web Server and the server instance. Default: WarnClient Dynamically updatable: No |
| CalendarTwoDigitYearMax | Specifies the last year of the 100-year range for representing two-digit years. This setting determines how two-digit years in dates entered in the client are interpreted. For example, when the value is 2049, then two-digit years are interpreted as a year between 1950 and 2049. For example, if you were to enter 29, 49, or 50 for a year, it would be interpreted as either 2029, 2049, or 1950, respectively. If you wanted the year to be interpreted as 2050, you'd have to enter the four-digit year 2050. Windows and Windows Server operating systems include a similar setting for 2-digit year entries. The CalendarTwoDigitYearMax setting of the Business Central Server instance overrides the Windows setting of the computer where the server instance is running. If you want to use the Windows setting of the computer, set CalendarTwoDigitYearMax to -1.Default: -1 Dynamically updatable: No |

You use this setting to filter out lower-level events from the log. For example, if you set this setting to Error, only Error and Critical events will be logged. Set to Off if you don't want to record telemetry events. When set to Off, events aren't emitted. Note: Telemetry trace events are recorded in the Business Central Server channel logs, which you can see in Event Viewer, under Applications and Services Logs > Microsoft > DynamicsNAV > Common > Admin. Default: Normal Dynamically updatable: Yes |
| ExternalTraceLevel | Specifies the lowest severity level of telemetry events from external proxies that you want the Business Central Server instance to emit if an error related to the external system occurs on the server instance. This setting pertains to systems and components that Business Central integrates with, like Dynamics 365 Sales (CRM/Xrm). The server instance listens for event traces from the external proxy. If an error occurs on the server instance, it will emit the last 10 telemetry trace events from the external proxy. The trace events can then be recorded in the Windows event log or picked up by other event trace collection tools. The setting has the following values, which correspond to the event severity levels (listed from highest to lowest level): Critical, Error, Warning, Information, Verbose, and Off. Events that have a lower severity level than the set value won't be emitted. For example, if you set this setting to Error, only Error and Critical events will be emitted. Set to Off if you don't want to emit any of these events. Default: Error Dynamically updatable: Yes |

Timeout format: [dd.]hh:mm:ss[.ff] Default: 12:00:00 Dynamically updatable: Yes |
| ReportMaxRows | Specifies the maximum number of rows that can be processed in a report. If exceeded, the report will be canceled by the server. You can also use MaxValue to indicate no limit. If you don't want a limit, set the value to MaxValue. For more information about how reports are canceled, see Report Generation and Cancellation Flow. Default: 1000000 Dynamically updatable: Yes |
| ReportPDFFontEmbedding | Specifies whether fonts are embedded in PDF files that are generated for reports when the report uses an RDLC report layout at runtime. This setting applies when reports are run and saved as PDF files on the client (from the report request page or print preview window) or on the server instance (by the SAVEAS function or SAVEASPDF function in AL code). Note: This setting doesn't apply when a report uses a Word report layout at runtime. You embed fonts in a PDF of a report to make sure that the PDF will use the same fonts as the original file, no matter where the PDF is opened and which fonts are installed on the computer. However, embedding fonts can significantly increase the size of the PDF files. Disabling font embedding decreases the size of the report PDF files. Note: This setting is a global setting for font embedding in report PDF files. You can override this setting on a report basis by the specifying the PDFFontEmbedding property. Default: Enabled Dynamically updatable: No |
| ReportingServicePort | Specifies the listening TCP port for rendering RDLC reports in a separate process that runs side-by-side with the server instance. The port is used for internal communications between server instance and the reporting service process. If you don't specify a port or set it to 0, a random port provided by the operating system is used. Default: 0 Dynamically updatable: No |
| CalculateBestPaperSizeForReportPrinting | Determines the paper size to use when printing reports from the client. If set to true, the system calculates which of the available paper sizes on the printer is best suited for printing, and then uses that paper size.If set to false, the printer's default paper size is used.Default: true |
Query settings
The following table describes settings related to query objects.
| Key Name | Description |

Important
Starting March, 2020, with 2019 release wave 2, Business Central only supports Transport Layer Security (TLS) version 1.2 or later. Upgrade to one of the latest supported Business Central release waves to remove support for earlier versions of TLS. If your solution or an add-on uses TLS 1.0 or 1.1, you must update that configuration or add-on to TLS 1.2 or later as soon as possible. For more information, see Blog post: Update to TLS 1.2 or later in Dynamics 365 Business Central in 2019 release wave 2.
Upgrade settings
The following table describes settings related to upgrade.
| Key Name | Description |
|---|---|
| IntegrationRecordsTableId | Specifies the ID of the application table that is used to store integration record IDs. This setting only applies when you upgrade from Business Central Spring 2019 (version 14) to Business Central 2019 release wave 2 (version 15). It ensures that current integration record IDs that are used in the application can be used as-is after upgrade. When a database is upgraded, a SystemId column will be added to the Integration Records table, and each record in the table will be assigned a SystemId value. The base application looks to this column to identify integration records. If you specify the Integration Records Table (ID) setting, the data upgrade process will set the SystemId to the same value as integration record ID; otherwise, the value is randomly assigned by the system. If you aren't upgrading to the Business Central 2019 release wave 2 base application, you can either skip this upgrade step by setting the value to 0. This is the case, when you've a fully customized application or you're only doing a technical upgrade. Or, if you 're using a different integration record table than 5151 Integration Record, set the value to ID of your custom integration record table. The custom integration record table must include the following columns as a minimum (with exact naming): Integration ID, Record ID, Table ID. Default: 5151 Dynamically updatable: Yes |
| DestinationAppsForMigration | Specifies the extensions that Microsoft and 3rd-party extensions have a dependency on. The dependencies typically include the base application, system application, and test application. Only use this setting when upgrading from Business Central Spring 2019. The setting is used during the data upgrade process. If configured, when an extension is published, the server instance will automatically modify the manifest of the extension to include the required dependencies. Default: Dynamically updatable: No |
External event settings
APPLIES TO: Business Central 2023 release wave 2 (version 23) and later
The following table describes parameters related to the external business events functionality. Learn more about business events on Business Central.
| Key Name | Description |
|---|---|
| ExternalEventsEnabledServiceLevel | Specifies whether the business events functionality is enabled at the server level. When disabled, this functionality can't be enabled at the environment level. However, when enabled, it can be overridden (disabled) at the environment level. Default: Enabled Dynamically updatable: No |
| ExternalEventsEnabledEnvironmentLevel | Specifies whether the business events functionality is enabled by default at the environment level. This setting can be used in conjunction with the 'EnableExternalEvents' environment setting to override behavior for specific environments. If the server setting 'ExternalEventsEnabledServiceLevel' is disabled, however, this setting is ignored. Default: Enabled Dynamically updatable: Yes |
| ExternalEventsActivityLogRetentionDays | Specifies the number of days records in the External Event Activity Log table are retained. Default: 7 Dynamically updatable: No |
| ExternalEventsActivityLogCleanupBatchSize | Specifies maximum number of records to remove from the External Event Activity Log table during cleanup as a part of a single transaction. Default: 50000 Dynamically updatable: No |
Using Business Central Administration Shell to modify server instance settings
The Business Central Administration Shell includes several Set- cmdlets that enable you to create and modify Business Central Server instances.
The main cmdlet for configuring a server instance is the Set-NAVServerConfiguration cmdlet. You can use this cmdlet to change any of the configuration settings that are listed in the previous sections. To change a configuration setting, you set -KeyName parameter to the Key Name that corresponds to the setting, and set the -KeyValue parameter to the new value. For example, you can change the value for DatabaseServer to DatabaseServer.Domain.Com for the server instance named MyInstance by executing this cmdlet:
Set-NAVServerConfiguration -ServerInstance "MyInstance" -KeyName "DatabaseServer" -KeyValue "DatabaseServer.Domain.Com"
Modifying dynamically updatable settings
For dynamically updatable settings, use the -ApplyTo parameter to specify how to apply the change. The change can be written directly to the configuration file (CustomSettings.config) and applied to the current server instance state. The option you choose will determine whether a server instance restart is required for the change to take effect. The parameter has three options, as described in the following table:
| Option | Description |
|---|---|
| ConfigFile | Saves the change to the configuration file of the server instance. The change won't take effect until the server instance is restarted. |
| Memory | Applies the change only to the server instance's current state. The changes take effect immediately, without having to restart the server instance. The change is stored in memory. The next time the server instance is restarted, it reverts to the setting in the configuration file. |
| All | Applies the change to the server instance's current setting state (in memory) and to the configuration file. The changes take effect immediately, without having to restart the server instance. |
For example, the following command sets the value for the MaxStreamReadSize key to 42424242, without having to restart the server instance.
Set-NAVServerConfiguration -ServerInstanceMyInstance -KeyName MaxStreamReadSize -KeyValue 42424242 -ApplyTo Memory
