C_ARSUM Ariba Supplier Management Practice Question
When a supplier is invited to register, which Ariba component validates that they are an existing entity on the Ariba Network?
⚠ Common exam trap
Candidates often confuse the Ariba Network Lookup Service with the internal ERP validation process, overlooking that the Network lookup is specifically for preventing duplicate Ariba account creation.
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
✓
The Ariba Network Global Lookup Service.
The Ariba Network uses a unique identifier, the ANID (Ariba Network ID), to track company entities. During registration, the system performs a lookup to prevent duplicate accounts. This is critical for maintaining clean master data; creating duplicate supplier records leads to fragmented spend analysis and reconciliation errors in downstream ERP systems, which complicates reporting and strategic supplier management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Supplier Registration Request object.
Why it's wrong here
The registration request is the document for gathering information, not the validation engine for network identity. While it may contain data to assist in manual verification, it does not possess the algorithmic logic to query the global Ariba Network for duplicate entity detection.
- ✓
The Ariba Network Global Lookup Service.
Why this is correct
The Global Lookup Service queries the Ariba Network database to identify if a company already possesses an ANID. This validation step is essential for enforcing entity uniqueness and ensuring that the supplier correctly links to their existing network identity, avoiding the creation of redundant accounts.
- ✗
The ERP Vendor Sync Service.
Why it's wrong here
The ERP sync service operates after the registration is complete and is concerned with transferring data to the internal financial system. It has no role in verifying the identity of a supplier on the Ariba Network, as its primary function is downstream data integration and mapping.
- ✗
The Supplier Lifecycle Master Data Repository.
Why it's wrong here
The repository is a database that stores the supplier information collected during the lifecycle. It is a passive storage system that does not provide active network validation services. It relies on the registration process to send it verified data, rather than performing the network identity lookup itself.
