NEW QUESTION # 41
You write a test codeunit that verifies that an error is raised when a sales order without lines is posted.
Which combination should you use?
Answer: D
Explanation:
Test codeunits use Subtype = Test, and each test procedure is marked with the [Test] attribute.
The asserterror keyword expects the following statement to fail; if no error occurs, the test fails.
TestRunner codeunits are used to run test codeunits and to handle results, not to define individual tests.
NEW QUESTION # 42
A company has an on-premises Business Central instance named TEST The instance uses Windows authorization and a developer services port of 7149 Visual Studio Code is installed on the same server.
You create a new AL project but cannot download the symbols.
The launch json file contains the following code:
You need to download the symbols.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
Answer: A,D
Explanation:
You are working on an on-premises Business Central instance and unable to download symbols for a new AL project. The current configuration in launch.json does not allow you to download symbols, and you need to make corrections.
Key Points in the Scenario:
* Instance name is TEST.
* Developer services port is 7149.
* Windows authentication is being used.
Correct Answers:
* A. Change the server Instance parameter to TEST.
* The serverInstance parameter must match the name of the Business Central instance, which is TEST in this scenario. You need to modify this to reflect the correct instance name.
* B. Add the port: 7149 parameter.
* Since the developer services are using port 7149, you need to specify this in the launch.json file by adding the port parameter with the value 7149.
Incorrect Options:
* C. Change the name parameter to TEST: The name parameter is just a label and does not affect downloading symbols, so changing this won't help.
* D. Change the authentication parameter to UserPassword: The authentication method is already set to Windows, which is valid for this scenario. Changing it to UserPassword is unnecessary unless specified by the system.
* E. Check which server the instance is installed on and replace http://localhost with the correct IP address: Since the server is on the same machine as Visual Studio Code (as specified), localhost is correct.
NEW QUESTION # 43
You create an ' AddltemsToJson " procedure and publish it.
The procedure fails to run.
You need to fix the errors in the code.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
Answer:
Explanation:
Explanation:
* In line 13, replace the Add method with Insert. = NO
* In line 15, replace the WriteTo method with ReadFrom. = NO
* Change the ItemObject variable type from JsonObject to JsonToken. = NO
* Move line 08 in the beginning of REPEAT .. UNTIL. = YES
The provided code is intended to serialize a list of items from the Item table into a JSON array format. Here is a breakdown of the code and the necessary corrections:
* In line 13, " ItemsArray.Add(ItemObject) " : This line is correctly using the Add method to add the ItemObject to the ItemsArray . The Add method is the correct method to use for adding items to a JsonArray . Therefore, there is no need to replace Add with Insert .
* In line 15, " ItemsArray.WriteTo(RequestText) " : The WriteTo method is used correctly to serialize the ItemsArray into a JSON formatted string and store it in the RequestText variable. The ReadFrom method is used for the opposite operation, i.e., to deserialize a JSON formatted string into a JsonArray
, which is not the goal in this context. Hence, no change is needed here.
* Change the ItemObject variable type from JsonObject to JsonToken : The ItemObject variable is intended to hold JSON objects representing individual items, making JsonObject the appropriate type.
JsonToken is not a type used in this context within AL for Business Central, and thus the variable type should remain as JsonObject .
* Move line 08, " Clear(ItemObject) " : This line should be moved inside the repeat loop to ensure that the ItemObject is cleared for each item in the loop. Placing it before the repeat would only clear it once before the loop starts, which could lead to incorrect serialization as the previous item ' s properties would not be cleared from the ItemObject .
The logic for serializing records into JSON is a common operation when interfacing with APIs or web services in Business Central, and the pattern shown in the code is typical for such operations.
NEW QUESTION # 44
A company is setting up a sandbox environment.
You observe the following issues in Visual Studio Code:
* When you open the User Settings window, no AL command is available
* In the Problems tab. the error 'The target page Customer List for the extension object is not found' is displayed.
You need to identify a solution for each issue.
Which solutions should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
No AL command in User Settings:The correct solution is to Install the AL Language extension.
* This issue arises when the AL Language extension is not installed in Visual Studio Code, which is required to work with AL projects in Business Central.
Error in the Problems tab:The correct solution is to Download Symbols.
* This error typically occurs when the symbols (metadata for pages, tables, etc.) are not downloaded, and Visual Studio Code cannot resolve the reference to the Customer List page. Downloading symbols should fix the problem.
