Microsoft Dynamics 365 Business Central Developer Sample Questions:
You need to define the properties for the Receipt No. field in the Non-conformity table when storing the information to the purchasing department 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:
field(3; " Receipt No. " ; Code[20])
{
DataClassification = CustomerContent;
TableRelation = " Purch. Rcpt. Header " . " No. " where ( " Buy-from Vendor No. " = field( " Vendor No. " ));
}
* Field Declaration:
* The field(3; " Receipt No. " ; Code[20]) part defines the field in the table with ID 3 and type Code with a length of 20. This field will hold the receipt number.
* DataClassification:
* CustomerContent is selected for the DataClassification property, which categorizes the data for privacy and compliance management. This aligns with Business Central ' s recommendations for handling sensitive data in customer-related tables.
* TableRelation Property:
* The TableRelation property links the " Receipt No. " field to another table, which in this case is the " Purch. Rcpt. Header " table. This ensures that only valid receipt numbers from the Purchase Receipt Header table can be selected or entered in this field.
* Relation Filter:
* The filter condition is applied using the where clause. It ensures that the Receipt No. is only from the Purchase Receipt Header records where the " Buy-from Vendor No. " matches the " Vendor No. " of the current record.
* The condition field( " Vendor No. " ) is selected from the drop-down as shown in the image. This links the vendor information in the non-conformity table to the receipt in the Purchase Receipt Header table.
* By linking the " Vendor No. " fields, you ensure that only receipt numbers from the correct vendor are available, which improves data consistency and reduces errors during data entry.
* References to AL Language:
* The TableRelation property is frequently used to create references between tables in Business Central. In this case, the correct relationship between the " Purch. Rcpt. Header " and the Non- conformity table is established using the TableRelation and filter.

Correct Answer: A 🗳️
Explanation: Only visible for ValidVCE members. You can sign-up / login (it's free).
You have a column in a report.
You receive the following warning from CodeCop:
"Field 'Home Page' is marked for removal. Reason: Field length will be increased to 255.. AL(AL0432) " You have the following code:
1 column(CompanyHomePage; CompanyInformation. " Home Page " )
2 {
3 }
For each of the following statements, select Yes if the statement is true, Otherwise, select No.
NOTE: Each correct selection is worth one point.
Correct Answer:
Explanation:
1. Create a custom Home Page field for the Company information table.
* Selection: No
* Reasoning: Creating a custom field (e.g., 50000 " My Home Page " ) creates a disconnected data silo.
The standard application uses the standard " Home Page " field. If you create a custom one, it will be empty unless you write additional code to sync it, and it won ' t be populated by standard pages. The correct approach is to either use the replacement standard field (if one exists) or suppress the warning until you can refactor.
2. Enclose Line 1 within #pragma warning disable AL0432 .. #pragma warning restore AL0432.
* Selection: Yes
* Reasoning: This is the standard, correct " Code update " to manage specific deprecation warnings (AL0432). It allows you to continue using the field temporarily (e.g., during a transition period while the field is Obsolete: Pending) without breaking the build, and it limits the suppression strictly to the lines of code that require it, rather than blinding the entire project to deprecations.
3. Disable the AL0432 rule in the ruleset.
* Selection: No
* Reasoning: While this technically stops the warning from appearing, it is considered bad practice.
Disabling the rule in ruleset.json suppresses AL0432 for the entire project , meaning you might miss other critical deprecation warnings that you actually need to address. It is a configuration change, not a focused " code update " to manage a specific warning.
4. Remove or comment the column and then put it back after the field length is increased.
* Selection: No
* Reasoning: Removing or commenting out the column breaks the report functionality immediately (the data will disappear from the report). Furthermore, relying on " putting it back later " is not a valid strategy for continuous development; you need the code to work now . If the field is marked for removal, it may not exist " later " in its current form, so simply uncommenting it in the future might fail entirely.
A company plans to optimize its permission sets.
The company has the following permission sets:
You need to provide the following implementation for a third permission set:
* Create a new Permission Set C that is a composite of Permission Set A and Permission Set B.
