How-to Index

How-to Guide

1. Create a formula field and call IFERROR

Entry path: Add Field → Formula

1. Open the multidimensional table that you want to edit.
2. Click Add Field on the toolbar.
3. Select Formula as the field type.
4. Enter a formula that includes IFERROR in the formula editor.
5. Continue filling in the parameters you need.

Success Criteria

• Interface result: A new formula field is added and the formula editor is open.
• Next action available: You can continue entering functions, parameters, and nested expressions.

Tips While Using

• Common mistake: If you use a text field instead of a formula field, you will not be able to enter the function correctly.
• Environment note: You need edit permission for the current table.

2. Review the IFERROR parameter format

Entry path: Formula Editor → Function Library → IFERROR

1. Open the function help or function list in the formula editor.
2. Select IFERROR.
3. Review the function parameter structure.
4. Enter the expression to test and the fallback value for error cases.

Reference format:

IFERROR(value, value_if_error)

Success Criteria

• Interface result: You can see the IFERROR function name and parameter structure.
• Next action available: You can continue completing the formula in the expected format.

Tips While Using

• Common mistake: If the parameter order is incorrect, the returned result may not match your expectation.
• Environment note: Parameter content should match the field types used in your formula.

3. Write and save a basic example

Entry path: Formula Editor

1. Enter a basic IFERROR example in the formula field.
2. For example, enter an expression that returns a fallback value when an error occurs.
3. Click Confirm to save the formula.
4. Check whether the formula result is displayed correctly in the record.
5. Change the related source data and observe whether the result refreshes.

Example:

IFERROR(A/B, 0)

Success Criteria

• Interface result: After saving, the formula field shows a calculated result instead of an error code.
• Next action available: When source data changes, the result updates automatically.

Tips While Using

• Common mistake: If the fallback value type is very different from the original result type, later display or logic checks may be affected.
• Environment note: If a referenced field is blank or mismatched in format, check the source data first.
