What is a truth about rating suppliers in SAP Ariba?

Rating suppliers in SAP Ariba is closely tied to the context in which interactions occur. One of the essential truths is that you can rate suppliers only if you have engaged with them in a meaningful way, ensuring that the feedback is based on direct experience rather than assumptions or hearsay. This is why the option regarding the requirement to have interacted with suppliers is significant; it emphasizes the quality and relevance of the rating process.

Additionally, the stipulation that ratings can be given only once per posting reflects a structured approach to supplier evaluation, preventing multiple ratings that could skew the assessment of a supplier's performance. Therefore, both of these aspects contribute to the credibility and utility of supplier ratings within SAP Ariba, highlighting that the process is designed to be fair and based on actual experiences.

By requiring interaction for ratings and limiting the number of ratings per posting, SAP Ariba ensures that evaluations maintain integrity, are constructive, and are relevant to future procurement decisions.
