What do dimensions and values represent in account posting rules?

In the context of account posting rules within Workday Financials, dimensions and values play distinct and complementary roles in defining how transactions are categorized and processed. Dimensions act as the broader categories or attributes that provide context to the financial data. For instance, these might include elements like cost centers, departments, or business units. Each dimension essentially narrows down the context of the data, indicating specific characteristics related to the transaction.

Values, on the other hand, represent specific instances or items under a given dimension. When we consider the logic behind how these components interact, it becomes clear that dimensions typically require an "AND" relationship—indicating that multiple dimensions must apply together to qualify a transaction for posting under a certain rule. Conversely, values establish an "OR" relationship, meaning that any of the listed values under a dimension can be valid for a transaction. This allows for more flexibility in how transactions meet the posting criteria.

Thus, understanding that dimensions operate under an "AND" logic while values adhere to "OR" logic explains why the correct interpretation is that dimensions mean AND, and values mean OR. This distinction is crucial for effectively configuring account posting rules and ensuring accurate financial reporting and compliance within Workday.
