Build and extend tables and pages in Business Central

Short answer

C BlankZero is one of the table field properties you are allowed to change in a table extension to the base application.

Question

A company plans to meet new regulatory requirements. The regulator has issued new tax tiers. You need to update the base application table by using a table extension. Which table field property can you change?
  1. CalcFormula
  2. DecimalPlaces
  3. BlankZero Correct Answer
  4. AutoFormatType

Key Takeaways

Properties you can change in a table extension are limited to presentation-related attributes such as Caption, Comments, DecimalPlaces, and BlankZero. Structural properties that affect the physical table definition cannot be altered.

A table extension can modify only a limited set of table field properties on fields inherited from the base application. BlankZero, which controls whether zero amounts are displayed as blanks, is among the properties that are explicitly changeable in a table extension.

Common mistake: Do not assume that every field property is extensible. Trying to change a property that the platform does not allow in a table extension will cause a compilation error, so choose only the documented changeable properties.

Expert Analysis

Why the Answer Is Correct

Option C is correct because BlankZero is a documented table field property that a table extension is permitted to modify on an inherited base table field. The scenario asks which property can be changed via a table extension, and BlankZero fits that rule directly. Community consensus (93 votes) and multiple commenters, including examenesArb, confirm BlankZero as the answer.

Why the Other Options Are Wrong

Option A (CalcFormula) defines how a flow field calculates its value and is not a property you change in a table extension. Option B (DecimalPlaces) is changeable, but it is not the property the question is targeting given the regulatory display requirement, and the community did not select it. Option D (AutoFormatType) is also not the property being asked about here and is not the consensus answer.

Community Comment Notes

bkik simply states 'BlankZero is correct,' and examenesArb points to the official table property overview as the source confirming the changeable properties.

    Answer is C. DecimalPlaces cannot be set for table extensions, so B is NOT correct
