A company plans to change a field on the Resource Card page in a Base Application. You need to hide the field "Unit Price" from the Resource Card page. Which code snippet should you use? A. B. C. D.

Question

Options

• Aaddlast ("Unit Price") { Visible = false; }
• Bmodify("Unit Price") { Enabled = false; }
• Caddlast ("Unit Price") { Enabled = false; }
• Dmodify("Unit Price") { Visible = false; }

• A
  4% (1)
• B
  13% (3)
• C
  4% (1)
• D
  79% (19)

Explanation

Option D is correct because modify is the proper keyword for changing properties of an existing field on a Base Application page - "Unit Price" already exists on the Resource Card, so you modify it rather than adding it. Setting Visible = false completely hides the field from the UI, which is exactly what "hide" means in Business Central AL.

Option B is close but wrong: Enabled = false only grays out the field and makes it non-interactive, but it remains visible on the page - that's disabling, not hiding.

Options A and C both use addlast, which is for adding new controls to a page. Since "Unit Price" already exists in the Base Application, using addlast would cause a compilation error; you must use modify to change existing controls.

Memory tip: Think "M-V: Modify to Vanish" - you Modify existing fields, and Visible = false makes them vanish. If you want to disable (dim), use Enabled; if you want to disappear, use Visible.
