In the Bill of Materials content in SAP Best Practices, which of the following accelerators are at solution level?

In the context of SAP Best Practices, the accelerators that are at the solution level are those that provide foundational insights and are applicable across various scenarios and implementation areas. The correct choice, which pertains to "Master data overview," fits this description perfectly.

The Master Data Overview serves as a comprehensive guide that outlines essential master data components required for effective management within the Bill of Materials (BOM) framework and provides clarity on how this data is utilized. It assists organizations in understanding the foundational elements that need to be established to ensure a smooth implementation and configuration process.

On the other hand, while test scripts, configuration documents, and software and delivery requirements are important components within the SAP environment, they tend to be more specific to individual projects or scenarios rather than being broadly applicable at the solution level. Test scripts are generally tailored to specific test cases, configuration guidelines vary by implementation needs, and software and delivery requirements focus on the technical prerequisites necessary for a specific deployment. Thus, "Master data overview" distinctly represents an overarching framework useful across different instances and serves a pivotal role in providing a solid groundwork for BOM management within SAP Best Practices.
