The Cost Center Allocation Segmented Object Detail (SOD) is specifically designed for scenarios where financial costs need to be distributed across multiple cost objects. When a user selects a value in a Cost Center Allocation SOD, the system uses predefined allocation rules associated with that value to automatically derive and populate the corresponding cost centers and their allocation percentages. This directly fulfills the requirement of deriving cost objects from the SOD value.

A. Grid SOD: This SOD type is used for capturing multiple line items of data in a tabular format, such as itemized expenses or detailed time entries, not for deriving cost objects.

B. Cost Center Attribute SOD: This SOD type is used to capture additional descriptive information (attributes) related to a selected cost center, rather than deriving the cost object itself.

C. Custom Field SOD: This is a generic SOD used for capturing unique data not covered by standard types. It lacks the specific, built-in logic for cost distribution and derivation.

"Segmented Object Detail Types". This guide details the purpose of each SOD type. The section on "Cost Center Allocation SOD" explicitly states its function is to enable the distribution of costs to multiple cost centers based on a single SOD value selection.

"Configuration Guide for Core Functionality". In the chapter on Financial Data Configuration

section "Configuring Segmented Object Details

" the guide explains that the Cost Center Allocation type is the designated tool for creating rules that derive cost object assignments. (Reference: Chapter 5
