C_ARSUM Ariba Supplier Management Practice Question
A supplier manager is building a qualification template for a commodity where suppliers must provide a tax identification number in a fixed national format. The manager wants the system to reject submissions that do not match the required pattern before the questionnaire reaches an internal reviewer. Which configuration should the supplier manager apply?
⚠ Common exam trap
Candidates often confuse data collection controls such as required fields or attachments with actual format validation, which only a regular expression rule provides.

Correct answer & explanation
✓
Apply a regular expression validation rule to the tax identification question
Format enforcement on typed questionnaire answers is achieved with regular expression validation, which evaluates the supplier's entry against a pattern at the moment of submission. When the pattern does not match, the response is blocked, so malformed tax identification numbers never reach an internal reviewer and data quality is enforced at the source.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Make the tax identification question a required text field with a maximum length
Why it's wrong here
A required text field with a maximum length only forces an answer and limits characters; it does not validate the national format. Suppliers could still submit malformed values that satisfy the length limit, so the questionnaire would reach the internal reviewer with invalid data, which is precisely what the manager wants to prevent.
- ✓
Apply a regular expression validation rule to the tax identification question
Why this is correct
Regular expression validation in SAP Ariba Supplier Management questionnaire templates checks the entered value against a defined pattern at submission time. Configuring a regex that matches the national tax ID format causes non-conforming entries to be rejected before the response is routed to an internal reviewer, satisfying the requirement to block invalid submissions early.
- ✗
Enable an internal approval task before the questionnaire is sent to the supplier
Why it's wrong here
An internal approval task placed before supplier submission reviews the template or the request, not the supplier's entered value. It cannot inspect the tax identification number the supplier types, so an invalid format would still pass through to the reviewer. The control point is in the wrong stage of the process.
- ✗
Add an attachment question asking the supplier to upload a tax certificate
Why it's wrong here
An attachment question collects a document but performs no format validation on typed values. The supplier could still enter an incorrect tax identification number in a text field, and the reviewer would have to detect the mismatch manually. This approach shifts validation to a human and does not reject invalid submissions automatically.
