Correct Answer: D,E 🗳️
You are creating a view of a customer list in AL.
The existing Balance Due (LCY) column must be the first column of the page. You plan to display only the customers whose names start with B.
You need to add the properties and code segment to obtain this result.
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.
Correct Answer:
Explanation:
You develop a table named Contoso Setup and a page.
You plan to use No. Series to automatically assign a unique number to data entries. You set up No. Series on the Vendor Nos. field of the Contoso Setup table.
You need to apply the No. Series Design Pattern to the trigger Onlnsert().
Which four code segments should you use to develop the solution? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.
Correct Answer:
Explanation:
Here is the correct sequence of the four code segments:
* if " No. " = ' ' then begin
* ContosoSetup.Get();
* ContosoSetup.TestField( " Vendor Nos. " );
* NoSeriesManagement.InitSeries(ContosoSetup. " Vendor Nos. " , xRec. " No. Series " , 0D, " No. " , " No. Series " ); end;
* Check for empty value: The standard pattern for OnInsert is to only assign a number automatically if the user has not manually entered one. Therefore, you start with if " No. " = ' ' then begin.
* Retrieve Setup: You must retrieve the setup record to access the configured No. Series code. The singleton pattern for setup tables uses ContosoSetup.Get();.
* Verify Configuration: Before attempting to use the series code, best practice dictates you ensure it is actually populated in the setup table. ContosoSetup.TestField( " Vendor Nos. " ); checks this field.
* Initialize Series: Finally, you call the InitSeries function.
* Argument 1 (Source): ContosoSetup. " Vendor Nos. " is the field containing the Series Code (as stated in the prompt).
* Argument 2 (Previous): xRec. " No. Series " handles standard renaming/validation logic.
* Argument 4 & 5 (Targets): " No. " and " No. Series " are the fields on the current record being updated.
* Note: The other available InitSeries block is incorrect because it tries to read a field named " No.
Series " from the ContosoSetup table, which does not match the prompt ' s description.
You need to use a query data type to retrieve requited data.
How should you complete the code ' To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Correct Answer:
Explanation:
You are retrieving data using a query data type . The following code snippet needs to be completed:
* If QueryA... : The correct option here is Open . This opens the query and prepares it for data retrieval.
* While QueryA... : The correct option here is Read . This reads through the query results one row at a time.
* If QueryA...: Open
* While QueryA...: Read
A company uses Business Central.
The company plans to use a translation file in an extension. The extension has a caption that should not be translated.
You need to prevent the caption from being translated.
What should you do?

- B. Delete the Caption property.

- D. Add the Locked = true parameter to the Caption.
- E. Copy the same caption for each language in the translation file.
