An SAP Datasphere Analytic Model is a specialized information view designed for analytical consumption. Its core component is a central fact source that contains the quantitative data (measures) to be analyzed. The designated object in the SAP Datasphere Data Builder to serve as this primary source is a view with the semantic type "Fact". This fact view is then enriched within the Analytic Model by associating it with various dimensions, which provide the business context for the measures.

A. Business entities of semantic type Dimension: Business Entities are created in the Business Builder, a higher semantic layer, and consume Data Builder objects like Analytic Models; they are not sources for them.

C. Tables of semantic type Hierarchy: Hierarchies are used to structure attributes within a dimension. They are associated with the model but are not the central fact source itself.

D. Remote tables of semantic type Text: Text tables are used to provide descriptions for dimension attributes. They lack the quantitative measures required to serve as a fact source for an Analytic Model.

1. SAP Help Portal - Creating an Analytic Model: This official documentation explicitly states the required source for an Analytic Model. It says

"You start by selecting a source view of semantic type Fact or Analytical Dataset

or a source table of semantic type Fact or Relational Dataset." This directly supports that a view of semantic type "Fact" is a valid source.

2. SAP Help Portal - Semantic Type: This page defines the purpose of different semantic types. It clarifies that the "Fact" semantic type is used for entities that "contain transaction data that you want to analyze and use for modeling an analytic model." This confirms its role as the primary source.
