NEW QUESTION # 36
You create a Business Central report.
You need to insert values on the Request page to be saved for the next time the report is run.
What should you do?
- A. Declare a Savevalues' variable and assign it to true on the OnOpenPage () trigger.
- B. Set the SaveValues property to true.
- C. Set the Use Request Page property to true.
- D. Set the Transact! on Type property to Update.
Answer: B
Explanation:
To ensure that the values inserted on the Request page of a Business Central report are saved for the next time the report is run, the SaveValues property (D) should be set to true. This property is available on the Request page of the report and, when set to true, allows the system to remember the values entered by the user, so they do not have to re-enter them each time they run the report. This feature enhances user experience by reducing repetitive data entry and ensuring consistency in report parameters across multiple executions. The other options mentioned, such as setting the Transaction Type property to Update (A) or declaring a Savevalues variable in the OnOpenPage trigger (B), are not directly related to saving user input on a report's Request page.

NEW QUESTION # 39
You need to determine why the extension does not appear in the tenant.
What are two possible reasons for the disappearance? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
- A. The extension was published as PTE. and the Platform and Runtime parameters were not updated in the application file.
- B. The extension was not compatible with the new version within 60 days of the first notification.
- C. The extension was published as a DEV extension.
- D. The extension was published as PTE. and the Platform parameter was not updated in the application file.
- E. The extension was not compatible with the new version within 90 days of the first notification.
Answer: A,B
Explanation:
In the context of Microsoft Dynamics 365 Business Central, an extension may not appear in the tenant for several reasons, particularly after an upgrade to a new major version.
Option A suggests that the extension was published as a DEV extension, which typically would not cause it to disappear after an upgrade because DEV extensions are intended for development and testing within sandbox environments.
Option B indicates that the extension was not compatible with the new version within 60 days of the first notification. This is a likely reason because Microsoft enforces compatibility rules, and extensions that are not made compatible within the specified timeframe might be removed or disabled.
Option C refers to the extension being published as a PTE (Per-Tenant Extension) and mentions the Platform parameter not being updated. This could cause issues, but not specifically the disappearance of the extension after an upgrade.
Option D expands on Option C by adding that both the Platform and Runtime parameters were not updated in the application file. This is a critical aspect because if these parameters are not correctly set to indicate compatibility with the new version of Business Central, the extension could be disabled or removed.
Option E is similar to Option B but mentions a 90-day period. This option does not align with standard Business Central practices for version compatibility requirements.
Therefore, the two possible reasons for the disappearance of the extension in the tenant after an upgrade are that the extension was not compatible with the new version within the required timeframe (Option B) and that the extension was published as a PTE without the Platform and Runtime parameters being updated (Option D).

NEW QUESTION # 43
You are developing an app.
You plan to publish the app to Microsoft AppSource.
You need to assign an object range for the app.
Which object range should you use?
- A. custom object within the range 50000 to 59999
- B. divided by countries and use specific a country within the range 100000 to 999999
- C. an object range within the range of 7000000 to 74999999 that is requested from Microsoft
- D. custom object within the range 50000 to 99999
- E. free object within the standard range 1 to 49999
Answer: C
Explanation:
When developing an app for Microsoft AppSource, it is essential to use an object range that is specifically designated by Microsoft to avoid conflicts with other apps and the base application.
The correct object range to use is:
An object range within the range of 70000000 to 74999999 that is requested from Microsoft (D):
This range is reserved for AppSource apps. Developers need to request this range from Microsoft to ensure that the objects used in their extension do not conflict with those used by other extensions or by the base application. Using this reserved range helps maintain the integrity and compatibility of extensions published on AppSource.
It's important to note that the other ranges mentioned (A, B, C, and E) are not suitable for apps intended for AppSource. Ranges 50000 to 59999 and 50000 to 99999 are typically reserved for per- tenant customizations or partner solutions, not for distribution on AppSource. The standard range 1 to 49999 is reserved for the base application objects, and using an object range divided by countries (C) is not a standard practice for AppSource apps.

Answer: A,D,E
Explanation:
When developing an app for Microsoft AppSource, it is crucial to adhere to specific guidelines and standards to ensure compatibility and compliance. The three code analyzers you should activate are:
CodeCop (A): This is the default analyzer for AL language extensions. It enforces the AL Coding Guidelines, ensuring that the code follows best practices for readability, maintainability, and performance. It checks for a wide range of issues, from syntax errors to best practice violations, making it essential for any AL development.
PerTenantExtensionCop (D): This analyzer is specifically designed for extensions that are intended to be installed for individual tenants. It includes rules that ensure the extension does not interfere with the per-tenant customizations and adheres to the guidelines for extensions that can be safely installed and uninstalled without affecting the underlying application.
AppSourceCop (E): This analyzer is tailored for extensions that are intended for publication on Microsoft AppSource. It enforces additional rules that are specific to AppSource submissions, such as checking for the use of reserved object ranges and ensuring that all prerequisite dependencies are correctly declared. This is crucial for ensuring that your app meets all the requirements for listing on AppSource.
By activating these three analyzers, developers can ensure their app adheres to the standards required for AppSource, as well as maintain high code quality and compatibility with Business Central.
NEW QUESTION # 50
You need to call the Issue API action from the mobile application.
Which action should you use?
- A. POST /issues (88122e0e-5796-ec11 -bb87-000d3a392eb5)/copy
- B. POST /issues (88122e0e-5796-ec11 -bb87-000d3a392eb5)/Copy
- C. POST/issues (88122e0e-5796-ec11-bb87-000d3a392eb5yMicrosoit.NAV.copy
- D. POST/issues(88122e0e-5796-ec11-bb87-000d3a392eb5)/MicrosoftNAV.Copy
- E. PATCH /issues {88122 eOe-5796-ed 1 -bb87-000d3a392eb5)/Mkrosotl.NAV.Copy
Answer: B
Explanation:
In the context provided by the case study, when calling an API action from a mobile application, the correct format for a POST request to an action in Business Central typically involves specifying the entity (/issues), the ID of the entity (88122e0e-5796-ec11-bb87-000d3a392eb5), and the action to be called (/Copy). The action name should match the exact name as defined in the AL code, which is case-sensitive.
Option A is incorrect because it uses a non-standard format for the action call.
Option B uses the PATCH method, which is generally used for update operations, not for calling actions.
Option C is correct as it uses the POST method, which is appropriate for calling actions, and correctly specifies the entity, ID, and action name.
Option D is incorrect because the action name /copy is in lowercase, while AL is case-sensitive, and it should match the case exactly as defined in the code.
Option E incorrectly adds 'MicrosoftNAV' before the action name, which is not standard for calling actions in Business Central APIs.
Hence, the correct action to use when calling the Issue API action from the mobile application is given in Option C.
NEW QUESTION # 51
You need to allow debugging in an extension to view the source code. In which file should you specify the value of the allowDebugging property?
- A. settings.json
- B. launchjson
- C. app.json
- D. rad.json
Answer: C
Explanation:
To enable debugging in an extension and allow the source code to be viewed, the allowDebugging property should be specified in the app.json file (C). The app.json file serves as the manifest for an AL project in Microsoft Dynamics 365 Business Central, defining the project's properties, dependencies, and features. By setting the allowDebugging property to true in this file, developers enable the debugging of the extension's source code, facilitating troubleshooting and development. This is essential for analyzing the behavior of the extension and identifying issues during the development process.
