Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.coherent.global/navigation/service-documentation.md). # Service Documentation From the [Folder overview](/navigation/folder-overview.md), selecting a service opens the **Service Documentation** page. This includes the processed metadata about the Excel file and the associated Spark service version. The information is split into multiple tabs. After choosing a specific service from the [Folder overview](/navigation/folder-overview.md), select the ![Service documentation](https://2714190325-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2Fc7fek1ZgAUH5MA3m5pH8%2Fuploads%2FqTfng99IaaA3tLAq2IJJ%2Fimage.png?alt=media\&token=a75a85b9-d8a2-4f5d-b9c1-ad2a78890c8b) icon from the service sidebar. ## Overview The overview screen presents a summary of key details about the Spark service. * High level statistics from the Excel workbook. * The number of **Calls**, **API users**, and **Test cases run**. * The number of calls made by user. * The number of calls made by a particular **Call purpose**. **Call purpose** is an additional [Execute API (v3)](/spark-apis/execute-api/execute-api-v3.md#request_meta) that can be provided with the API call. * By default, the call figures include all API calls. To view only calls that are from Spark [SHELL](/assistant/shell/what-is-shell.md), select the **By calls logged** dropdown and select **By Shell submissions**. ## Upload details Information about the Excel file and the [Neuron](/build-spark-services/neuron.md) conversion to code. | Key | Value | | -------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------- | | **Version** | Spark semantic version number. | | **Filename** | Filename of the uploaded file. | | **File size** | File size of the uploaded file. | | **Number of sheets** | Number of worksheets in the Excel workbook. | | **Cells with data** | **Cells with data** corresponds with Excel's **Workbook Statistics** feature that counts the number of used cells and formulas. | | **LAMBDA functions in workbook** | Indicator for the presence of any Excel `LAMBDA()` functions in the workbook. | | **Date added** | The time the file was uploaded to Spark. | | **Added by** | User account of the user who uploaded the service version. | | **Spark environment URL** | This is the base URL that is used to invoke [Spark APIs](/spark-apis/getting-started.md). | | **File UUID** | A generated universally unique identifier (UUID) for the uploaded file. | | **File hash** | `MD5` hash generated for the uploaded file. | | **Conversion time** | The time to process the conversion of the Excel file. | | **OriginalServiceHash** | `SHA-256` hash of the originally uploaded Excel file, i.e. Original Service. Can be used to confirm if the files used are the same. | | **CompiledOutputHash** | `SHA-256` hash of the compiled Neuron Wasm. Can be used to confirm whether the distributed code is the same as what was originally compiled. | | **Upload log** | View the **Upload log** that is shown during the upload. | ## Version details Properties specific to the service version. | Key | Value | | ----------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Version** | Spark [semantic version](https://semver.org/) number. | | **Version label** | Text field that attaches to version numbers across the Spark user interface. This can be provided as part of the upload journey. | | **Release notes** | Text field to describe the purpose of the upload. This can be provided as part of the upload journey. | | **Description** | This is another field that can be used to describe the service. This can be provided as part of the upload journey. | | **Tags** | Tags that were added to the service. | | **Date modified** | Date the service was updated. | | **Modified by** | User account of the user who uploaded the service version. | | **Effective from** | See [Manage service versions and effective dates](/build-spark-services/manage-service-versions-and-effective-dates.md) for more information about how this is used. This is entered as part of the upload journey. | | **Effective until** | See [Manage service versions and effective dates](/build-spark-services/manage-service-versions-and-effective-dates.md) for more information about how this is used. This is entered as part of the upload journey. | | **Default service type** | Defines the default service type used as a default for this Spark service. Service type relates to the Spark `compiler_type` used (e.g. `Neuron` or `XConnector`). | | **Compiler version** | Compiler version used for this service version. | | **Enable API Call History** | This setting determines whether the [API Call History](/navigation/api-call-history.md) is enabled. | | **Direct addressing outputs enabled (Neuron 1.16.0 and earlier)** | See [Execute API (v3)](/spark-apis/execute-api/execute-api-v3.md) [Execute API (v3)](/spark-apis/execute-api/execute-api-v3.md#request_meta) `requested_outputs`for more details. For [Neuron](/build-spark-services/neuron.md) `1.17.0` and later this property is ignored. | | **Batch size override** | Sets the number of records that are processed at a time in the [Testing Center](/navigation/testing-center.md). | | **Parameterset compatibility group** | This is only applicable to services that contain `Xparameter`. Every Service version is tied to a parameter set compatibility group. | | **Version ID** | A generated universally unique identifier (UUID) for this service version. This can be used to identify a service as part of the [Execute API](/spark-apis/execute-api.md). | ## Service details Properties that apply across service versions. | Key | Value | | ----------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Initial version author** | User account of the user who uploaded the service version. | | **Compiler version service update** | Define which Neuron version to use for a service update. Learn more about how to configure this in [Tenant configuration](/tenant-administration/tenant-configuration.md#choose-the-neuron-compiler-version-for-additional-service-versions). | | **Public API enabled** | This determines whether this version of a service can be accessed without authentication. Read more: [Authorization - Public APIs](/spark-apis/public-apis.md) | | **Public API URI** | This is one of the endpoints that can be used to access the Public API endpoint. | | **XConnector URL** | If API call the `compiler_type` is `XConnector`, the API call will be sent to this URL. | | **Service ID** | A generated universally unique identifier (UUID) for this particular service. This can be used to identify a service as part of the [Execute API](/spark-apis/execute-api.md). | ## Inputs and Outputs List of the mapped Spark inputs and outputs. | Key | Value | | ----------------- | --------------------------------------------------------------------------------------------------------- | | **Name** | The name of the input/output. | | **Sheet** | The Excel worksheet where the input/output was defined. | | **Address** | Within the Excel worksheet, the range address where the input/output was defined. | | **Data type** | `Date`, `NUMBER`, or `TEXT`. | | **Initial value** | For **Inputs**, any value that exists in the cell or evaluated from a formula from an input/output range. | | **Description** | This is read from Excel's **New Name Comment** field. | ## **Edit a service property** A number of the **Service Documentation** properties can be modified. 1. Change any of the editable fields on the **Service Documentation** screens. 2. Click **Update**. 3. Choose between making a new version of the service or editing the same service version. 4. Follow the prompts to proceed with the change.
