Question 250

An integration team tries to add a property to an existing Business Central API page through a pageextension. The developer recommends the following change: Create a separate custom PageType API page with a defined API contract. Which technical explanation most directly justifies it in this case?

  1. A page view stores reusable presentation/filter settings over existing records instead of creating a separate data store
  2. Field classification communicates the nature of data for governance and privacy operations but is not itself an access-control grant
  3. The tableextension augments an extensible table's schema while leaving the Microsoft table object unchanged
  4. Business Central API pages cannot be extended with pageextension objects; new custom API pages define their own endpoints

Explanation

Correct Answer

D:

Business Central API pages cannot be extended with pageextension objects; new custom API pages define their own endpoints. It connects the proposed action to the exact failure or requirement—An integration team tries to add a property to an existing Business Central API page through a pageextension. Confirmation would be the new endpoint appears with the specified publisher, group, version and entity names and responds to authorized requests.

Incorrect Answers

A:

That mechanism explains why the alternative action—define a page view and filtering behavior rather than duplicating the underlying record table—helps in another case. It does not justify the proposed fix here; Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints. The distinguishing requirement is: An integration team tries to add a property to an existing Business Central API page through a pageextension.

B:

That mechanism explains why the alternative action—set the dataclassification metadata on the custom al table field—helps in another case. It does not justify the proposed fix here; Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints. The distinguishing requirement is: An integration team tries to add a property to an existing Business Central API page through a pageextension.

C:

That mechanism explains why the alternative action—add a tableextension object with a properly numbered custom field on the existing table—helps in another case. It does not justify the proposed fix here; Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints. The distinguishing requirement is: An integration team tries to add a property to an existing Business Central API page through a pageextension.

Question 251

An integration team tries to add a property to an existing Business Central API page through a pageextension. The team implemented a change aligned with this plan: Create a separate custom PageType API page with a defined API contract. Which acceptance result specifically verifies that the reported problem is resolved?

  1. The new endpoint appears with the specified publisher, group, version and entity names and responds to authorized requests
  2. The named view consistently returns only matching rows while the source table remains unchanged
  3. Field metadata reports the intended classification while effective user permissions remain governed separately
  4. A new field persists through a sandbox app upgrade and is visible to code through the target table

Explanation

Correct Answer

A:

The new endpoint appears with the specified publisher, group, version and entity names and responds to authorized requests. This is stronger than an unrelated health check because the desired design action is create a separate custom pagetype api page with a defined api contract, and Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints. The local requirement is: An integration team tries to add a property to an existing Business Central API page through a pageextension.

Incorrect Answers

B:

This would verify define a page view and filtering behavior rather than duplicating the underlying record table, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: An integration team tries to add a property to an existing Business Central API page through a pageextension. The decisive local proof is the new endpoint appears with the specified publisher, group, version and entity names and responds to authorized requests.

C:

This would verify set the dataclassification metadata on the custom al table field, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: An integration team tries to add a property to an existing Business Central API page through a pageextension. The decisive local proof is the new endpoint appears with the specified publisher, group, version and entity names and responds to authorized requests.

D:

This would verify add a tableextension object with a properly numbered custom field on the existing table, which addresses a different engineering need. It does not demonstrate that the current issue is resolved: An integration team tries to add a property to an existing Business Central API page through a pageextension. The decisive local proof is the new endpoint appears with the specified publisher, group, version and entity names and responds to authorized requests.

Question 252

An integration team tries to add a property to an existing Business Central API page through a pageextension. A targeted trial still reproduces the original gap after the team attempted this change: Create a separate custom PageType API page with a defined API contract. Which repair directly addresses the remaining defect?

  1. Correct the view's filters and placement in the intended list page or pageextension
  2. Replace the invalid API pageextension with a properly versioned new API page
  3. Correct the field's DataClassification property and use security permissions for actual access restriction
  4. Correct the extension target or field definition and republish the tableextension rather than editing the base table

Explanation

Correct Answer

B:

Replace the invalid API pageextension with a properly versioned new API page. This directly addresses the remaining defect for the requirement—An integration team tries to add a property to an existing Business Central API page through a pageextension. It restores the mechanism described here: Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints.

Incorrect Answers

A:

This correction is for the separate condition: A sales supervisor wants an easily reusable list view for overdue quotes without writing a second table. It would not directly restore the intended behavior in this situation: An integration team tries to add a property to an existing Business Central API page through a pageextension. Here, replace the invalid api pageextension with a properly versioned new api page, because Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints.

C:

This correction is for the separate condition: A regional vendor adds an employee medical note field and wants its sensitivity visible to data governance tools. It would not directly restore the intended behavior in this situation: An integration team tries to add a property to an existing Business Central API page through a pageextension. Here, replace the invalid api pageextension with a properly versioned new api page, because Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints.

D:

This correction is for the separate condition: A wholesale distributor needs an export-control flag stored on Item records while retaining vendor upgrade compatibility. It would not directly restore the intended behavior in this situation: An integration team tries to add a property to an existing Business Central API page through a pageextension. Here, replace the invalid api pageextension with a properly versioned new api page, because Business Central api pages cannot be extended with pageextension objects; new custom api pages define their own endpoints.

Question 253

A partner wants to expose a new endpoint by extending a standard API page object with extra entities. Which single AL development or architecture change best resolves this requirement without redesigning unrelated workflows?

  1. Define a page view and filtering behavior rather than duplicating the underlying record table
