C_ARSUM Ariba Supplier Management Practice Question
When a supplier is invited to an SAP Ariba project, what is the first action they must take to participate?
⚠ Common exam trap
Many candidates incorrectly select 'Completing the supplier profile' or 'Signing the contract' as the first step, overlooking that Ariba Network registration is the mandatory prerequisite for all other interactions.

Correct answer & explanation
✓
Complete the account registration on the Ariba Network.
The first step for a supplier is to register on the Ariba Network. This registration creates the necessary secure link between the supplier and the buyer organization. It provides the supplier with a unique login and account profile, which is essential for secure communication, data submission, and auditability throughout the life of the engagement, ensuring all interactions are tracked against a verified and persistent entity identifier.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Submit their tax and bank details directly via email.
Why it's wrong here
Sending sensitive financial data like tax and bank details via email is a major security risk. SAP Ariba provides secure, encrypted forms for this purpose within the registration portal. Encouraging or allowing email-based data submission would expose the organization to potential fraud and violate fundamental data privacy and security compliance policies.
- ✓
Complete the account registration on the Ariba Network.
Why this is correct
Registering on the Ariba Network is the fundamental prerequisite. It establishes the secure account identity required to access the buyer’s project, submit mandatory documentation, and participate in subsequent sourcing or qualification activities. Without this registration, the supplier cannot securely interact with the buyer’s platform or access the assigned project-related tasks.
- ✗
Call the procurement manager to verify the invitation.
Why it's wrong here
Calling the manager is an inefficient way to handle system access and does not fulfill the technical requirements for secure authentication. The invitation process includes built-in verification mechanisms. Relying on manual phone verification would not grant the necessary digital credentials to access the secure portal and complete the onboarding project tasks.
- ✗
Request a temporary username from the IT helpdesk.
Why it's wrong here
Ariba handles user registration natively. Requesting credentials from the IT helpdesk of the buyer company is not possible as suppliers are external entities. The Ariba Network account registration process is self-managed by the supplier, ensuring that the responsibility for account security and access credentials remains with the vendor themselves.
