C_ARSUM Ariba Supplier Management Practice Question
A new buyer is creating a supplier registration project in SAP Ariba Supplier Management. The buyer wants to ensure that the supplier provides a valid tax identification number in a specific format. Which field type should the buyer use in the registration questionnaire?
⚠ Common exam trap
The trap here is selecting a number field assuming tax IDs are numeric, but many tax IDs include letters or special characters, requiring a text field with regex validation.

Correct answer & explanation
✓
Text field with a regular expression validation pattern.
To enforce a specific format for a tax identification number, a text field with a regular expression validation pattern is the correct choice. Regular expressions can define patterns for alphanumeric characters, length, and structure, ensuring the supplier enters a valid tax ID. Other field types like number, date, or dropdown do not provide the flexibility to validate a custom format.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Number field with a minimum and maximum value range.
Why it's wrong here
A number field only validates that the input is numeric and within a range; it cannot enforce a specific alphanumeric format such as a tax ID that may contain letters or dashes. This would not meet the requirement for a specific format. The tax ID often includes letters, so a number field is insufficient.
- ✗
Date field with a calendar picker.
Why it's wrong here
A date field is used for date inputs and cannot validate a tax identification number format. It would be entirely inappropriate for capturing a tax ID. The scenario requires a text-based format validation, not a date.
- ✗
Single-select dropdown with predefined tax ID formats.
Why it's wrong here
A single-select dropdown allows choosing from a list of options but does not allow the supplier to enter their actual tax ID. It would only capture the format type, not the value. This does not satisfy the need to collect the tax identification number in a specific format.
- ✓
Text field with a regular expression validation pattern.
Why this is correct
A text field with a regular expression validation pattern enforces a specific format for the tax identification number. This allows the buyer to define the exact pattern required, ensuring the supplier enters data correctly. It is the appropriate field type for format enforcement in SAP Ariba questionnaires.
