NEW QUESTION # 10
You need to parse the API JSON response and retrieve each order no. in the response body.
How should you complete the code segment? To answer select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Code Segment Analysis:
* The AL code is trying to read JSON data from a response and process it to extract subcontracting order numbers. It uses JsonToken, JsonObject, and JsonArray to work with the JSON data.
* JToken.ReadFrom(Data): This line reads the incoming JSON data and converts it into a token. It processes the full JSON body so you can start working with it.
* JToken.SelectToken("results"): This line selects the part of the JSON containing the results array.
The key "results" is where the JSON response data is expected to be found.
* JsonArray: Once the results are extracted, they are stored as an array, and each element in the array (which is expected to contain subcontracting order numbers) is processed.
* SubcontractingOrderNo: The extracted order_no from the JSON is stored in this variable.
Breakdown of Steps:
* JToken.ReadFrom(Data): This step reads the entire JSON response.
* JToken.SelectToken("results"): This step selects the results array from the JSON response.
* JArray.AsArray(): This step converts the selected results token into a JSON array that can be iterated over.
* GetValueAsText(JToken, 'order_no'): This step retrieves the order_no from each element in the array.
Correct Code Completion:
* JToken.ReadFrom(Data): This is the correct method to read the incoming JSON response, as it will convert the string into a JsonToken that can be further processed.
* JToken.SelectToken("results"): This is the correct method to extract the results array from the token.
This method looks for the key "results" in the JSON and retrieves the relevant array.
Final Code Segment:
al
Copy code
procedure ReadJsonData(Data: text)
var
JToken: JsonToken;
JObject: JsonObject;
JArray: JsonArray;
SubcontractingOrderNo: Code[20];
begin
if Data = '' then
exit;
JToken := JToken.ReadFrom(Data); // Step 1: Read the JSON response data.
JToken := JToken.SelectToken('results'); // Step 2: Select the "results" array.
JArray := JToken.AsArray(); // Convert the token into a JSON array.
foreach JToken in JArray do begin
SubcontractingOrderNo := GetValueAsText(JToken, 'order_no'); // Retrieve the order number.
end;
end;
* JToken.ReadFrom(Data): This reads the raw JSON data string and converts it into a JSON token that can be processed.
* JToken.SelectToken("results"): This extracts the results array from the JSON data.
* JArray.AsArray(): Converts the token into an array so we can iterate over it.
* GetValueAsText(JToken, 'order_no'): Extracts the order_no value from each item in the array.
NEW QUESTION # 11
You create the following Vendor table and Item table in Business Central.
You require the following data set to assign vendors to items.
You need to create a query to assign the vendors.
Which three code blocks should you use to develop the solution? To answer, move the appropriate code blocks from the list of code blocks 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.
Answer:
Explanation:
Explanation:
To create a query that assigns vendors to items in Business Central, use the following code blocks in sequence:
* dataitem(Vendor; Vendor)
* dataitem(Item; Item)
* DataItemLink = "Vendor No." = Item.Vendor_No;
Creating a query:In Business Central, a query object is used to combine data from multiple tables. You start by specifying each table as a data item. In this case, you would start with the Vendor table and then the Item table. After specifying the data items, you need to link them together. The DataItemLink property is used to establish a relationship between two data items based on a common field. Here, you are linking the Vendor and Item tables on the "Vendor No." field, which is present in both tables. This link ensures that the query will return a dataset that includes related records from both tables based on the vendor number. The order of the code blocks ensures the logical flow and relationships between tables as required for the query.

Hotspot Question
A company plans to import and export data with Business Central.
You must configure an XMLport that provides the following implementation:
- Specifies import 01 export on the Request page at run time
- Formats the data in a non-fixed length CSV format
You need to create the XMLport.
How should you complete the code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Both
You are configuring an XMLport for Business Central with the following requirements:
Specifies import or export on the Request page at runtime.
Formats the data in a non-fixed length CSV format.
XMLport Configuration:
Specifies import or export on the Request page at runtime.
The Direction property must be set to Both.
This allows the XMLport to both import and export data depending on user selection during runtime.
Box 2: Format= VariableText
Formats the data in a non-fixed length CSV format.
The Format property must be set to VariableText.
VariableText is used for delimited text formats like CSV, which do not have a fixed length for fields.

NEW QUESTION # 14
You are creating a new Business Central report.
You plan to use triggers and functions to dynamically create a dataset and control the report behavior.
You must provide the following implementation.
* Run when the report is loaded.
* Run when the data item is iterated for the last time.
* Skip the rest of the report.
You need to select the triggers and functions for the report.
Which triggers and functions should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
* Runs when the report is loaded: OnInitReport
* Runs when the data item has been iterated for the last time: OnPostDataItem
* Use this function to skip the rest of the report: CurrReport.Quit()
1. Requirement: Runs when the report is loaded.
* Selection: OnInitReport
* Reasoning: The OnInitReport trigger is the very first event that fires when the report object is instantiated (loaded). It runs before the request page is displayed, making it the correct choice for " when the report is loaded. "
* Contrast: OnPreReport runs after the request page, just before the data processing starts.
2. Requirement: Runs when the data item has been iterated for the last time.
* Selection: OnPostDataItem
* Reasoning: The OnPostDataItem trigger executes immediately after the report has finished iterating through all records belonging to that specific data item.
* Contrast: OnPreDataItem runs before the loop starts, and OnAfterGetRecord runs repeatedly during the loop (for every record).
3. Requirement: Use this function to skip the rest of the report.
* Selection: CurrReport.Quit()
* Reasoning: The CurrReport.Quit() function completely aborts the execution of the report, effectively " skipping " everything else remaining in the report logic.
* Contrast: CurrReport.Skip() only skips the current record processing and moves to the next record. CurrReport.Break() exits the current data item loop but proceeds to the next data item (if any) or finishes the report normally.
