C_ARSUM Ariba Supplier Management Practice Question
A supplier manager is setting up a new qualification template and wants to ensure that suppliers cannot submit their responses without providing a valid tax identification number. The tax ID must follow a specific format of two letters followed by six digits. Which field type should be used for this requirement?
⚠ Common exam trap
The trap here is assuming that any field type can enforce a pattern, when only text fields with regex validation provide that capability.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Text field with a regular expression validation rule
To enforce a specific alphanumeric format like two letters followed by six digits, a text field with a regular expression validation rule is the correct choice. The regex ensures the supplier's input matches the required pattern before submission, providing immediate validation and preventing invalid data entry.
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 range constraint
Why it's wrong here
A number field only accepts numeric input and cannot accommodate the two-letter prefix. A range constraint would limit numeric values but would not enforce the alphanumeric pattern. This field type is unsuitable for a tax ID that includes letters.
- ✗
Attachment field for uploading a tax certificate
Why it's wrong here
An attachment field allows document uploads but does not validate the format of a tax ID entered as text. It shifts the burden of verification to manual review and does not prevent submission without a valid tax ID. The requirement is for format validation at entry, not document collection.
- ✓
Text field with a regular expression validation rule
Why this is correct
A text field combined with a regular expression validation rule enforces a specific format. The regex can be defined as ^[A-Za-z]{2}\d{6}$ to require two letters followed by six digits. This ensures suppliers cannot submit invalid tax IDs, meeting the requirement precisely.
- ✗
Single-choice question with predefined tax ID formats
Why it's wrong here
A single-choice question presents predefined options, which is impractical for a tax ID that varies per supplier. It cannot validate the actual format of the supplier's unique tax ID. This approach would not enforce the two-letter-six-digit pattern.
