This update enhances the analytic reporting feature by adding a 'product category' field to the core accounting model. This allows users to group and analyze expenses by product category within their reports, providing more granular insights into spending patterns. It's an improvement that streamlines reporting and analysis.

Add the related (non-stored) 'product_category' field on the account.analytic.line model to make it available in the Analytic Reporting "Group By"
