35. Frage
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
A company creates a Business Central app and a table named MyTable to store records when sales orders are posted.
Users report the following issues:
- The users receive permission errors related to MyTable.
- Users are no longer able to post sales orders since installing the
new app.
- The users cannot access the list page created in MyTable.
You need to resolve the user issues without creating new permission sets. You must use the principle of least privilege.
Solution: Decorate the event subscriber used for inserting data in MyTable by entering (InherentPermissions(PermissionObjectType::TableData. Database::MyTable. 'R')] Does the solution meet the goal?
Antwort: B
Begründung:
Using InherentPermissions in an event subscriber with the specified syntax could potentially resolve the permission issues related to MyTable, provided that the permissions specified (in this case, 'R' for Read) align with the minimum necessary for the users to perform their tasks. This approach allows the app to grant permissions dynamically based on the context of the event subscriber, which in this case is involved with inserting data into MyTable. By granting Read permission at the event level, it ensures that users have the necessary permissions to interact with MyTable in the context of the operations facilitated by the event subscriber, without needing to alter existing permission sets or grant broader permissions than necessary. This solution adheres to the principle of least privilege by ensuring that permissions are granted only within the narrow scope needed for specific operations, thereby potentially resolving the reported user issues in a secure and controlled manner.

- The users cannot access the list page created in MyTable.
You need to resolve the user issues without creating new permission sets. You must use the principle of least privilege.
Solution: In the MyTable object, add the property InherentPermissions = RI.
Does the solution meet the goal?
Antwort: B
Begründung:
The property InherentPermissions is used to automatically grant permissions to the table object it is applied to, but setting it to Rl (which seems to be a typo and should likely be 'RL' for Read and Insert permissions) is not sufficient in this scenario. The issues reported by the users suggest that they need more than just read and insert permissions on MyTable. Since users are unable to post sales orders, they likely need Modify, Delete, or Execute permissions on certain tables or objects related to the sales order process. Additionally, the inability to access the list page created in MyTable could be due to lacking Read permissions on other related objects or pages. Therefore, merely setting InherentPermissions = RL on MyTable does not comprehensively address the users' permission issues, especially when considering the principle of least privilege. A more tailored approach to permissions, potentially involving adjustments to the app's code or configuration to ensure proper permissions are applied where necessary, would be needed.
37. Frage
A developer creates a profile for part-time shop supervisors and adds customizations.
You plan to add new requirements to the profile.
You need to analyze the code to understand the profile and make sure there are no errors.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Antwort:
Begründung:
Explanation:
The Part Time Shop Supervisor profile will be applied only to users with "Register Time" = true on User Setup: No Variables, procedures, and triggers cannot be added on page customization objects: Yes Line 10 should use extends instead of customizes: No In line 18, "Unit Cost" will be moved after "Costing Method": Yes The Part Time Shop Supervisor profile will be applied only to users with "Register Time" = true on User Setup.
* No
* The code doesn't contain any reference to the User Setup table or the Register Time field, so this is not correct. Profiles are not applied conditionally based on fields like this.
Variables, procedures, and triggers cannot be added on page customization objects.
* Yes
* Page customization objects are meant for UI modifications, such as moving or hiding fields. You cannot add variables, procedures, or triggers in a page customization object.
Line 10 should use extends instead of customizes.
* No
* In AL, when customizing a page within a profile, you use customizes rather than extends. Extends is used when modifying base application objects, but customizes is used to customize pages within a profile.
In line 18, "Unit Cost" will be moved after "Costing Method".
* Yes
* The code in line 18 is correct. The moveafter directive will move the "Unit Cost" field after the " Costing Method" field on the page layout.
38. Frage
You need to handle the removal of the Description field and the Clone procedure without breaking other extensions.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
NOTE: More than one order of answer choices is correct. You will receive credit for any of the correct orders you select.
Antwort:
Begründung:
Explanation:
In Business Central, when you need to handle the removal of fields and procedures to ensure that other extensions are not affected by these changes, you typically follow a two-step deprecation process. This allows other developers and users to adapt to the changes before they are fully enforced. Here are the steps to handle the removal:
* Mark as Obsolete: In the first version where the decision to remove the field or procedure is made, you set the ObsoleteState to Pending and provide an ObsoleteReason. This doesn't remove the feature but indicates to users and developers that it will be removed in the future. This step is crucial for backward compatibility.
* Removal: In a subsequent version, after users have had time to adapt to the deprecation warning, you can then remove the field or procedure or set the ObsoleteState to Removed.
Based on these guidelines, here are the three actions you should perform in sequence:
* Set the Description field as ObsoleteState = Pending and ObsoleteReason = 'Not in use' in version
2.0.0.0.
* Set the Clone procedure as ObsoleteState = Pending and ObsoleteReason = 'Not in use' in version
2.0.0.0.
* Remove the Description field from the Issue table in version 2.0.0.1.
These steps will ensure that anyone using the Description field or Clone procedure will receive a warning about the pending deprecation before it is actually removed, thereby minimizing the impact on other extensions and providing a clear path for migration.
When handling the removal of fields and procedures in Microsoft Dynamics 365 Business Central, the process should be carried out in a way that allows other extensions or dependent features to adapt to the changes without causing immediate failures.
* Set Obsolete State and Reason for Description Field (Version 2.0.0.0): The first step involves marking the Description field as obsolete by setting the ObsoleteState to 'Pending'. This is a non-breaking change, signaling to other developers and users that the field is planned for removal in a future version.
An ObsoleteReason should also be provided to explain why the field is being deprecated.
* Set Obsolete State and Reason for Clone Procedure (Version 2.0.0.0): Similarly, the Clone procedure should be marked as obsolete with the ObsoleteState set to 'Pending'. This indicates that the procedure is no longer in use and will be removed in the future. Providing an ObsoleteReason is best practice as it explains the rationale behind the decision.
* Remove the Description Field (Version 2.0.0.1): In the subsequent version, after the developers and users have been given time to adapt to the deprecation notice, the Description field can be safely removed from the Issue table. This is considered a breaking change, hence it is done after the field has been marked as obsolete in a previous version.
The reason for not removing the Description field and Clone procedure immediately in version 2.0.0.0 is to avoid causing runtime errors for any extensions or integrations that may depend on these components. By following this sequence, you provide a clear deprecation path that helps maintain the stability of the overall system while evolving the schema.
39. Frage
A company is implementing Business Central.
In the per-tenant extension, TableA Header and TableA Line are document tables, and TableB Header and TableB Line are document history tables.
The company requires that the resulting dataset of query objects contain the following records:
* All records from TableA Header even if no matching record value exists in the linked TableA Line
* Records from TableB Header where a match is found in the linked TableB Line field You need to configure the linked data item to generate the required dataset.
Which SqlJoinType should you use? To answer, move the appropriate SqUoinTypes to the correct dataset requirements. You may use each SqlJoinType once, more than once, or not at all. You may need to move the split bar between panes or scroll to view content.
Antwort:
Begründung:
Explanation:
* Include all records from TableA Header even if no matching record value exists in the linked TableA Line: LeftOuterJoin
* Include only matched records from TableB Header: InnerJoin
In SQL and similarly in Business Central when defining table relationships in query objects, the type of join determines how records from one table are combined with records from another table. Here's what each join type means in the context of the company's requirements:
* LeftOuterJoin:
* A LeftOuterJoin includes all records from the 'left' table (TableA Header) and the matched records from the 'right' table (TableA Line). If there is no match, the result is NULL on the side of the 'right' table. This is why it fits the requirement to include all records from TableA Header even if there is no matching record in TableA Line.
* InnerJoin:
* An InnerJoin includes records when there is at least one match in both tables. So, it will only include records from TableB Header where a corresponding match is found in TableB Line. If there is no match, the records from TableB Header will not appear in the result set. This aligns with the requirement to include only matched records from TableB Header.
By using these join types, the company can ensure that their dataset includes the appropriate records from the document tables and document history tables according to their specified requirements.
